• Can I install Whizzy for Emacs on a Mac (is Mac OS X a unix environment)?

  - by Vivi

  I think my question is pretty stupid, but here it goes: I am using Aquamacs, and I want to install the Whizzy mode. The website for Whizzy says that "it is designed for Unix platforms". I read that Mac OS X is unix certified, but does that mean I can install Whizzy on my mac? If yes, can I install and use it with Aquamacs or do I have to use the Emacs running from the terminal? PS: I don't know whether this question should be posted here or on SuperUser, but as Emacs users seem to hang out here more often, this is the place I chose.

• Port a Rails App from Windows to Mac or Linux

  - by Ryan Max

  Hello I've been a Rails developer on Windows for quite some time now, but I recently completed my biggest project yet (it's quite extensive, took me over a year to build) but I am having trouble deploying it. The combination of it's size, complexity and a windows environment is making it needlessly complex to deploy. I am thinking about getting an old mac mini and using it just for rails development. Either that or install unix on another box. Is there any way I can port my app to this mac or linux machine, without having to start over? I can't find any resources on the internets about this.

• WebGL on older Mac OS X versions (say 10.4)

  - by rotoglup

  Not really a programming related question but... I'd like very much to experiment with WebGL on my spare time. My current 'spare time' machine is a MacBook running Mac OS X Tiger (10.4.xx) and I'm unable to find a new browser supporting this OS. Firefox dropped support, Chrome too, and Safari idem. I read somewhere that this is due to a Quicktime bug that Apple won't fix. Does anyone have more information on this issue ? Does anyone have a clue or track to find a running implementation of WebGL on Mac OS X 10.4 ? Cheers,

• How do I install Ubuntu 13.10 from a partition on my Mac?

  - by Barry

  I am trying to install Ubuntu 13.10 on my Macbook Air. I've previously had no issue installing from a USB stick to this machine. However, I don't currently have access to a USB stick or any external media at all! What I've done so far is partitioned my SSD into 3 partitions. One holds OS X, another is a 5gb partition intended for the install ISO, and a third is intended to be the target for that install. The second two partitions are formatted as FAT. I've used dd (with and without bs=1m) to "burn" my ISO to the small 5gb FAT partition. I also at one point tried using hdituil to convert my ISO file to IMG and went through the same process with same result below. After "burning" my ISO to the small partition, I reboot into Refind. Refind sees my small 5gb partition perfectly well, and when I select that partition it loads GRUB appropriately. However, from here, regardless of what I choose, Ubuntu will start to load and then after a few minutes crash out to: BuzyBox V1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) Enter 'help' for a list of built in commands. (initramfs) unable to find a medium containing a live file system. I've Googled this error and found a number of people encountering it when trying to install from USB, but no solutions seem applicable to my case (installing from a partition on my SSD, to another partition on my SSD). Is there any solution to this, or do I just need to wait a few days until I have access to a USB stick? Many thanks in advance, and apologies for length -- I figured I'd err on the side of being exhaustive rather than having people suggest things I've already tried.

• Why can't I mount the Ubuntu 12.04 installer ISOs in Mac OS X?

  - by eric

  Over the past few days, I have downloaded both the 32 and 64 bit version of server and desktop to install on an Intel based PC. It is normal from within OS X to double click on an ISO and it will mount the ISO in the finder as well as within disk utility. When I attempt to mount any of the Ubuntu ISOs I downloaded, OS X returns the error message The following disk images couldn't be opened. The reason given for the error is no mountable filesystem. However, I am still able to open the ISO directly from disk utility and burn it to a DVD/CD. What has changed in this release to cause this? Is there something wrong with the current ISOs? The OS X machine I am using is only two weeks old and is having no issues with any other ISO.

• Opening a LWJGL window from a SWT app on Mac

  - by TomA

  I have a SWT app that opens a OpenGL window (using the LWJGL library) after a button is pressed. Works fine on Windows. On Mac, I get this error: 2010-03-05 02:28:25.315 java[1315:a07] [Java CocoaComponent compatibility mode]: Enabled 2010-03-05 02:28:25.316 java[1315:a07] [Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.100000 2010-03-05 02:28:25.317 java[1315:a07] Apple AWT Startup Exception : _createMenuRef called with existing principal MenuRef already associated with menu 2010-03-05 02:28:25.318 java[1315:a07] Apple AWT Restarting Native Event Thread The SWT window closes and then the app hangs, with no windows open. It looks like the SWT app doesn't shut down cleanly and leaves it's menu entries associated with it, which prevents the LWJGL window from opening. Mac OS X only wants one application menu. SWT doesn't free it's own menu and LWJGL wants to add another. Facts: A button in the SWT dialog is supposed to close the dialog and open a LWJGL window (org.lwjgl.opengl.Display). The button sets a static variable in the app to tell it what to do next after the SWT window is closed, so the LWJGL window is NOT being opened from a SWT callback directly. The button then closes the SWT window. I don't know the correct way of doing this but tried various combinations of shell.close, shell.dispose, display.close and display.dispose, none of them worked. They all close the window but the error occurs every time. Does anyone know what could be done to make this work?

• Problem trying to install PyCurl on Mac Snow Leopard

  - by Ldn

  Hi, My app needs to use PyCurl, so i tried to install it on my Mac but i found a lot of problems and error :( Requirement: First of all i've to say that the version of Python working on my Mac is 32 bit based, because i need to use WxPython, that needs 32 bit Python. For doing this i used: defaults write com.apple.versioner.python Prefer-32-Bit -bool yes To install PyCurl i used: sudo env ARCHFLAGS="-arch x86_64" easy_install setuptools pycurl And the terminal returned: Best match: setuptools 0.6c11 Processing setuptools-0.6c11-py2.6.egg setuptools 0.6c11 is already the active version in easy-install.pth Installing easy_install script to /usr/local/bin Installing easy_install-2.6 script to /usr/local/bin Using /Library/Python/2.6/site-packages/setuptools-0.6c11-py2.6.egg Processing dependencies for setuptools Finished processing dependencies for setuptools Searching for pycurl Best match: pycurl 7.16.2.1 Processing pycurl-7.16.2.1-py2.6-macosx-10.6-universal.egg pycurl 7.16.2.1 is already the active version in easy-install.pth Using /Library/Python/2.6/site-packages/pycurl-7.16.2.1-py2.6-macosx-10.6-universal.egg Processing dependencies for pycurl Finished processing dependencies for pycurl so i thought that pycurl was correctly installed and working.

• Mouse bugginess - SWFObject, Firefox 3 for Mac, and Flash

  - by justinbach

  I'm pulling my hair out over a problem I'm encountering on Firefox 3.5 & 3.6 on OS X. I'm using SWFobject to embed an AmMap of the US, which has rollover tooltips for various states. The rollovers are working fine in every other browser I've tested, but they're very buggy on FF for Mac--most of the time they don't show up at all, but if I persistently click a state that's supposed to have a hover event, I might catch a glimpse of the tooltip. Here's the code for the SWFObject embed (incidentally, this isn't being done in the document head due to templating reasons). The reason that the SWFObject initialization is wrapped in Jquery's document.ready handler is that the swf wasn't even appearing in FF 3.5.9 for mac until I added that in: $(document).ready(function() { var params = { quality: "high", scale: "noscale", allowscriptaccess: "always", allowfullscreen: "true", bgcolor: "#FFFFFF", base:"/<?php print LANG . "/locations/" ?>" }; var flashvars = { path: "", settings_file: "mapsettings", data_file:"mapdata" }; var attributes = { id: "flashmap", name: "flashmap" }; swfobject.embedSWF("/assets/flash/ammap.swf", "flashmap", "470", "300", "8", null, flashvars, params, attributes); }); Any feedback would be greatly appreciate...site goes live in 48 hours! Thanks!

• File-level filesystem change notification in Mac OS X

  - by Paul J. Lucas

  I want my code to be notified when any file under (either directly or indirectly) a given directory is modified. By "modified", I mead I want my code to be notified whenever a file's contents are altered, it's renamed, or it's deleted; or if a new file is added. For my application, there can be thousands of files. I looked as FSEvents, but its Technology Overview says, in part: The important point to take away is that the granularity of notifications is at a directory level. It tells you only that something in the directory has changed, but does not tell you what changed. It also says: The file system events API is also not designed for finding out when a particular file changes. For such purposes, the kqueues mechanism is more appropriate. However, in order to use kqueue on a given file, one has to open the file to obtain a file descriptor. It's impractical to manage thousands of file descriptors (and would probably exceed the maximum allowable number of open file descriptors anyway). Curiously, under Windows, I can use the ReadDirectoryChangesW() function and it does precisely what I want. So how can one do what I want under Mac OS X? Or, asked another way: how would one go about writing the equivalent of ReadDirectoryChangesW() for Mac OS X in user-space (and do so very efficiently)?

• Making RDoc Ruby Gem Default on Mac OS X

  - by jkale

  Hey all, I've recently installed RDoc version (2.4.3) through Ruby gems to replace the one shipped with Mac OS X (version 1.0.1). Unfortunately, I can still only use RDoc 1.0.1 when I call run "rdoc" at the command line. rdoc -v returns: RDoc V1.0.1 - 20041108 I tried amending the $PATH variable to point the first entry to the RDoc 2.4.3 folder but no luck. I couldn't find anything about this online either, so I thought I'd ask here. Cheers! Update: Running "gem list -d --version 1.0.1 rdoc" returns: *** LOCAL GEMS *** rdoc (2.4.3) Authors: Eric Hodel, Dave Thomas, Phil Hagelberg, Tony Strauss Rubyforge: http://rubyforge.org/projects/rdoc Homepage: http://rdoc.rubyforge.org Installed at: /usr/local/lib/ruby/gems/1.8 RDoc is an application that produces documentation for one or more Ruby source files Therefore, it's definitely the Mac OSX version of RDoc that's interfering with the Gems version. Update 2: I found out, using: `bash --debugger rdoc` that the old version of RDoc was in /opt/local/bin. I deleted it and added my gems directory to my $PATH `export PATH=/usr/local/lib/ruby/gems/1.8/gems/` I now have a fresh working copy of the latest RDoc!

• Apply a Quartz filter while saving PDF under Mac OS X 10.6.3

  - by olpa

  Using Mac OS X API, I'm trying to save a PDF file with a Quartz filter applied, just like it is possible from the "Save As" dialog in the Preview application. So far I've written the following code (using Python and pyObjC, but it isn't important for me): -- filter-pdf.py: begin from Foundation import * from Quartz import * import objc page_rect = CGRectMake (0, 0, 612, 792) fdict = NSDictionary.dictionaryWithContentsOfFile_("/System/Library/Filters/Blue \ Tone.qfilter") in_pdf = CGPDFDocumentCreateWithProvider(CGDataProviderCreateWithFilename ("test .pdf")) url = CFURLCreateWithFileSystemPath(None, "test_out.pdf", kCFURLPOSIXPathStyle, False) c = CGPDFContextCreateWithURL(url, page_rect, fdict) np = CGPDFDocumentGetNumberOfPages(in_pdf) for ip in range (1, np+1): page = CGPDFDocumentGetPage(in_pdf, ip) r = CGPDFPageGetBoxRect(page, kCGPDFMediaBox) CGContextBeginPage(c, r) CGContextDrawPDFPage(c, page) CGContextEndPage(c) -- filter-pdf.py: end Unfortunalte, the filter "Blue Tone" isn't applied, the output PDF looks exactly as the input PDF. Question: what I missed? How to apply a filter? Well, the documentation doesn't promise that such way of creating and using "fdict" should cause that the filter is applied. But I just rewritten (as far as I can) sample code /Developer/Examples/Quartz/Python/filter-pdf.py, which was distributed with older versions of Mac (meanwhile, this code doesn't work too): ----- filter-pdf-old.py: begin from CoreGraphics import * import sys, os, math, getopt, string def usage (): print ''' usage: python filter-pdf.py FILTER INPUT-PDF OUTPUT-PDF Apply a ColorSync Filter to a PDF document. ''' def main (): page_rect = CGRectMake (0, 0, 612, 792) try: opts,args = getopt.getopt (sys.argv[1:], '', []) except getopt.GetoptError: usage () sys.exit (1) if len (args) != 3: usage () sys.exit (1) filter = CGContextFilterCreateDictionary (args[0]) if not filter: print 'Unable to create context filter' sys.exit (1) pdf = CGPDFDocumentCreateWithProvider (CGDataProviderCreateWithFilename (args[1])) if not pdf: print 'Unable to open input file' sys.exit (1) c = CGPDFContextCreateWithFilename (args[2], page_rect, filter) if not c: print 'Unable to create output context' sys.exit (1) for p in range (1, pdf.getNumberOfPages () + 1): #r = pdf.getMediaBox (p) r = pdf.getPage(p).getBoxRect(p) c.beginPage (r) c.drawPDFDocument (r, pdf, p) c.endPage () c.finish () if __name__ == '__main__': main () ----- filter-pdf-old.py: end

• PNG's In Mac on Java cause massive CPU usage

  - by alexganose

  Hey, I've been having this problem for a while now and I was hoping someone could help. I make small games using Java on Mac OSX 1.6.3 and if I use PNG's as the image format my CPU usage by Java skyrockets to say 50% (on a very small 2D game). However if I use GIF as the format my CPU usage by Java stays constant at 10% which is reasonable. What is causing this problem?? It occurs on every game I develop using PNG's so I always just switch to GIF's. The problem is now that i need to use a PNG for its variable alpha properties rather than just plain transparency. This is not available using GIF's. The problem is present on Java SE 6 and previous versions. I am using an early 2009 Mac Book Pro 15". The problem does not occur on a Windows PC running the same game. The CPU usage due to Java using PNG's on a Windows PC (I have tried XP, Vista and 7) is always constantly low at ~10%. Any help would be greatly appreciated. Thanks :)

• Smarty/PHP loop not being passed to IE(Pc) or Chrome/FF(Mac)

  - by Kyle Sevenoaks

  Hi, I've been working on a site that has a lot of PHP/Smarty involved, I've been asked to re-skin a webstore checkout process, but during this we've discovered this issue. This particular quirk is one part of a tax calculation that doesn't get sent to the browser in IE for PC and Chrome/FF for the Mac. It's NOT in the output source in the browsers, but is in FF, Chrome and Opera on the PC. Here is the code that doesn't "work:" {foreach $cart.taxes.$currency as $tax} <div id="subTotalCaption2"><p style="width:100px;">{$tax.name_lang}:</p></div> <div id="taxAmount2"><p>{$tax.formattedAmount}</p></div> {/foreach} It's not a CSS issue as if you go all the way through the checkout process and then back to the order page (Not using the back button, using the on-site links) it works. There is another calculation on the last page of the process that does the same thing: {foreach from=$order.taxes.$currency item="tax"} <tr> <td colspan="{$colspan}" class="tax">{$tax.name_lang}:</td> <td>{$tax.formattedAmount}</td> </tr> {/foreach} I guess my question is what could cause this to not be read (Parsed?) in IE and the mac but other browsers do it fine on the PC. Thanks.

• Copy Windows 7 environment running on external drive to a new HDD partition on a Mac?

  - by sam

  My PC has just given up on me. It's getting a bit old so I took the HDD out and bought a Mac. I've put the PC's HDD into an enclosure, plugged it into the Mac and dragged across most of my files. I've got a couple of programs that are PC-only that I have to run from time to time, so I'd like to make a partition on the Mac and have Windows 7 installed there. I know how to set up a clean version of Windows in Boot Camp. Is there an easy way to copy over the environment on the HDD to the Mac's partition? I don't really need all the stuff on the PC, just the operating system. Is there a better way to do this other than having to deactivate Windows, then reactivate it on the Mac? I have a free upgrade to Windows 7 from Vista, thus I have an upgrade disc, not the full disc.

• Is is possible to change MAC address of a WiMAX USB adapter?

  - by Salman A

  Wondering if it is possible to change the MAC address of a WiMAX USB adapter (read WiMAX, not Wi-Fi) manufactured by Motorola, ZTE, Intel etc. I've tried a few tools that did changed the MAC address of the adapter to another valid MAC address (that I coped from another equipment made by same company) but then I was not able to connect to the network, the connection software took long time stating "obtaining IP address"; then few seconds after it got one said "lost IP address". Wondering if changing MAC address of such devices actually work.

• SSH from mac to linux -> start gnome-session -> X11 keyboard mapping all messed up.

  - by Justin

  I have 2 computers: echo.local is running Ubuntu 9.04. justin.local is running Mac OS 10.6.1. X11 version on the mac is 2.3.4. I open X11 on the mac, and open a new xterm window (Applications Menu - Terminal), everything is fine. Keyboard works as expected. I do ssh -X echo.local from the mac (connecting to the linux box), and from the linux command prompt, start xterm - everything is fine. Keyboard works as expected. I do gnome-session from the linux command prompt (through SSH), gnome launches, but keyboard mapping is ALL types of screwed up. If I kill gnome-session and open an xterm via ssh, keyboard mapping is still screwed up. If I then kill the SSH session entirely, and do X11 - Applications Menu - Terminal, opening a brand new xterm window on the mac with no SSH session running at all ... keyboard mapping is still screwed up. Only after I quit X11 and relaunch, is the keyboard mapping back to normal. Keyboard layout under GNOME is Apple-MacBook/MacBook Pro.

• How can I get the MAC address from my stolen laptop so the police can trace it?

  - by Ayman

  A week ago my HP Mini 110 was stolen. I reported to the police and they asked me about my Laptop's MAC address, which I don't know or had never heard about before. Is there any way to get the MAC address of my stolen laptop, as I have all the docs that prove my ownership of the laptop? I've contacted HP to give me the MAC address, but they told me that it should be taken from the set itself and they can't help.

• Mac Mini monitor on the move – can I use VNC or a portable monitor?

  - by Jjunju

  I have been investigating the possibility of using my PC to control my soon to arrive Mac Mini when on the move. I can't afford and hope you don't give me answers suggesting buying a MacBook. My Mac Mini is the high end type. Now I have seen that the only viable option seems to be VNC. But how does this work if I am not on a network? Does VNC work with an ad-hoc network? Can a PC be connected to a Mac on such a network? Can this network be configured once at home and then be available on startup on the move? If I have an iPhone, can I use it as my wifi? But then, how would I start the Mac Mini to make the connection, since it wouldn't have a screen on the move? Finally, are there any small portable screens one can carry in a bag?

• How to create iso dvd image for use with Mac OS X's "Disk Utility"?

  - by adolf garlic

  This seemed way easier on my pc. I would just pop a blank dvd in the drive, it asked what I wanted to do with it, to which I would respond, "burn dvd with nero" (paraphrasing), then I would pick "new" and just drag and drop the folders in there. Mac appears to have "Disk Utility" which just requires that I 'choose an image' but then doesn't bother to detail: how to do this what the options mean e.g. format "Mac OS Extended (Journaled)" is that ever going to be readable on a non Mac machine? I want to create an ISO standard DVD as per the 'default' you'd get on nero. All the stuff on the web points to doing things with 'Terminal' (the whole point of buying a Mac was to get away from command line jiggery pokery - I'm trying to burn some photos not land a friggin lunar module here!) Please, if you can just provide some simple instructions on what I need to achive this I'd be extremely grateful. Ta muchley in advance.

• How can I lock my Mac when I walk away?

  - by schnapple

  This has got to be an easy, trivial question but as a new Mac user, how can I lock my Mac when I walk away? On Windows this is dead simple - Win+L. Or hit Ctrl-Alt-Del and select "Lock this Computer" The best thing I've found for the Mac is to rig the screensaver to require password on wake, set a hot corner to fire off the screen saver, and do that as I leave. Which feels really "Windows 3.1" to me. Is there a Win+L-style method to quickly lock my Mac when I walk away?

• What Linux distro should I install on an old PowerPC Mac?

  - by rockit

  I'm trying to set up my brother–who has a PPC Mac with 1 GHz processor and 256 MB RAM–with a Linux distro that would allow him to surf the web on the device. If anyone knows of this Mac, they also know that support has faded for the latest browsers, rendering the device essentially useless when it comes to the web. Ideally I would have installed Jolicloud, but alas, it is only Intel Mac compatible... Please let me know if you have any suggestions for me!

• What do I need to write Japanese (kanji) on my Mac?

  - by Ken

  I have a Macbook, but it's slightly too old to use Mac OS X 10.6's trackpad Chinese input. I have a Wacom tablet, but even though Mac OS X has had tablet character recognition since 10.2 and now knows Chinese characters, they're separate enough that it apparently can't put these two together and read Chinese characters I write on my Wacom. But I'm sure somebody has a way to let me do this. What software do I need to let me write Japanese kanji on my Wacom tablet under Mac OS X?

• How do I crop an image in the Mac version of Microsoft Word?

  - by Bec

  I know how to do it in the Windows version of Word but I can't work out how in the Mac version. In Windows there's a crop tool where you can just drag to move the edges in to crop the image, how do I do that on the Mac? Also on the old version of Windows there was a command to delete the cropped sections of all images in a document to save file space, I can't find that in Word 2007 or Word for Mac.
