• Turn Off File Journaling, Then Turning It On?

  - by Yar

  One of my programs recommends that I turn off file journaling to minimize CPU usage. However, file journaling is important. Can I turn it back on when I'm done running that program, or is it not to be thought of as a toggle?

• Git can no longer open emacs as its editor

  - by mwilliams

  I'm running Git version 1.7.3.2 that I built from source, zsh is my shell, and emacs is my editor. Recently I started seeing the following: /usr/local/Cellar/git/1.7.3.2/libexec/git-core/git-sh-setup: line 106: emacs: command not found Could not execute editor My zshrc looks like the following so I can use the Cocoa build and the console binary provided with it. EMACS_HOME="/Applications/Emacs.app/Contents/MacOS" function e() { PATH=$EMACS_HOME/bin:$PATH $EMACS_HOME/Emacs -nw $@ } function ec() { PATH=$EMACS_HOME/bin:$PATH emacsclient -t $@ } function es() { e --daemon=$1 && ec -s $1 } function el() { ps ax|grep Emacs } function ek() { $EMACS_HOME/bin/emacsclient -e '(kill-emacs)' -s $1 } function ecompile() { e -eval "(setq load-path (cons (expand-file-name \".\") load-path))" \ -batch -f batch-byte-compile $@ } alias emacs=e alias emacsclient=ec And I also have export EDITOR="emacs" and have tried adding export GIT_EDITOR="emacs" (and swapping that out with "e") But whatever I try I can't get git to open emacs whenever I need to do a commit or an interactive rebase, etc etc...

• Any Suggestions on How to Soup Up/ Mod a MacBook Pro 13"?

  - by 5arx

  So I've got a mid-2009 MacBook Pro 13". Integrated GPU so not a games machine but fast enough for doing .Net development in VMs. I love the little thing and wanted to give it a Christmas present so thought I'd mod it up a bit and give it a boost. I'm probably going to go for a 500GB Seagate Momentus XT hybrid drive rather than full-on SSD (I need 500GB space) but was wondering if there are any other mods/tweaks people could suggest? I saw something online about swapping a HDD for the DVD drive and wondered if anyone had tried this or similarly drastic mods to the smallest of the MBPs. Cheers.

• Converting the encoding of a text file (Mac OS X)

  - by Casebash

  Okay, now that I can detect the encoding, I know that my encoding is using charset=iso-8859-1 instead of utf. How can I convert this?

• Mac, VNC and multiple monitors

  - by MarqueIV

  I asked a similar question here before but apparently I wasn't as clear as I had expected by the responses. That said, I'll try again. I have a Mac Pro with quad monitors which I would like to access remotely. I've been using VNC for this (either via screen sharing or a dedicated VNC client), which works, but the VNC protocol matches the physical layout/resolutions of attached monitors. One of the things I like about Microsoft's Remote Desktop (Terminal Server) client is that when you connect, it blanks out the local screens and sets the resolution to a client-specified setting. In other words, when natively running Windows, even though I'm running a physical 30" monitor flanked by 2 24" monitors as well as a 21" Cintiq monitor, I can set the Remote Desktop resolution to match my notebook's screen giving me a native, single-monitor configuration. As soon as I disconnect (and you log back in locally), the desktop un-blanks and the resolution resets back to the four physically attached monitors. Again, VNC works and yes I know I can use 5901, 5902...n to attach VNC to a specific monitor as opposed to the entire desktop, but I'm still at the mercy of trying to look at a 2560x1600 resolution on a 1280x800 screen. I'm left with either scaling (everything's too small) or panning/scrolling (it's like playing hide-and-seek with your documents!) SO... anyone know of any Mac-based remote software (client and server) that will let me connect to my Mac Pro and reset the resolution by the client, just like you can in Windows, or am I SOL?

• How to troubleshoot problems sharing internet connection via WiFi on Mac OS X

  - by sprugman

  I'm at a hotel, plugged into their network via ethernet on my MacBook. I want to share the connection via wifi to two other computers. I went to Prefs Sharing and set up internet sharing. I know it's working because my friend with a Mac access the net fine. My friend with the PC can see the network, but can't connect to it. In the sharing prefs, airport options, I chose these options: Channel: Automatic Enable encryption: yes WEP Key length 40-bit password length: 5 chars (as specified in the instructional text) Update: I tried it with encryption turned off, and it works. Of course, I'd rather not do that... Any ideas?

• Is it possible to code on two different computers simultaneously?

  - by Muhammad

  I want to work with another programmer and I want the source code to be live in real-time on both of our screens. Is this possible on the Mac OS x or Linux? We're going to be using OS X but occasionally we might need to add an Ubuntu computer too. Is there a way I can do this using ssh, any shell based program, or even a good GUI? I thought Coda might be capable of this but it's not really working. Anyone ever do this? I'm not look for a git/svn/or any other version control system. This is more of a live coding session. :)

• Reclaiming deleted disk space from file vault

  - by cbrulak

  I have my main user account encrypted with file vault. After deleting some data (like 20 GB) my free space on the hard drive hasn't change (yes I emptied the trash, confirmed that the files are actually gone, etc,etc). I also tried "erasing free space" in the disk utility app. I logged off, and rebooted and so far that space hasn't been reclaimed. I'm assuming file vault or disk utility has some method of reclaiming but I can't find it. Any ideas?

• Go back to 32-bit Java in OS X so I can use Chrome

  - by Mac Kris

  Recently Apple released a Java update. I mindlessly downloaded and installed it, thinking it must be good (I know that was stupid on my part). Now chrome doesn't work where sites require Java support. In terminal, java -version shows I have the 64bit version installed. I know Chrome does not support 64bit Java. I'd like to go back to the last version that worked for me, the 32-bit version. I don't want to use Safari or Firefox. I'd like Chrome to work. I have too much invested in customizing it to work with another browser.

• Sudden loss of Wi-Fi connectivity on OS X

  - by GJ.

  Occasionally while I work, without any special provocation, I lose connectivity via Wi-Fi. Other devices connected to the same wifi network have no interruption, and the problem gets resolved once I reboot my MacBook Air, so it's definitely a local problem. Observations: The Wi-Fi symbol in the menu indicates that I'm still connected, but apps can't actually connect neither to the Internet nor to other devices in the LAN. I can't connect to an alternate Wi-Fi network (e.g. Wi-Fi tethering via iPhone). I can connect to the Internet via iPhone USB tethering but this seems to only work some of the time. Only a reboot solves the problem but a regular restart gets stuck on a grey screen with rotating wheel (after all applications have closed) and I have to do a hard reset. How should I go about troubleshooting this? It used to happen very rarely but now is becoming more frequent (approaching once every 2-3 days on average).

• How Can I Set the OS X Dock to Show Instantly Instead of Waiting Half a Second in Snow Leopard?

  - by Patrik Björklund

  Having a MacBook Pro 13" I find myself trying to maximize the screen real estate constantly which have led me to put the dock at the right hand corner of the screen. Now in an attempt to save a few more pixels I decided to give autohiding of the dock a go and ran into a problem that have plagued me all night... When you toggle the switch to automatically hide the dock you get stuck with a small delay before it appears when hovering the edge of the screen. I have learnt that this is one of the many design principles Apple have put in use. In this case it appears to be their mission to save me from seeing the dock those few times when it's not intentional to touch the screens edge. In Windows there was a way to tweak this setting to have the menubar appear instantly by altering some registry value. Is there some way I can do this in Mac OS X?

• Piping the output of a program to Preview.app

  - by Abhay Buch

  I'm using an application (the dot program of the graphviz library) that generates a wide variety of file formats including PostScript and PDF. It can send the result to stdout or to a file. I'm currently sending it to a file and opening it with Preview. Is there any way to pipe the output and have it be read by Preview, so that I'd don't have to generate a file and have it lying around? This is going to be used by a number of people who won't know the internal structure of the generating script and I don't want to clutter their folders or complicate their lives. More generally, is there any way to take a program that sends its output to stdout and pass that output to an program that usually takes it's input from a file, without actually creating a file?

• How can I scan from Canon PIXMA MX700 without disabling OS X firewall?

  - by Justin Love

  I have a Canon PIXMA MX700 connected by ethernet. When I first bought it I was using OS X 10.4, and scanner-initiated scanning worked fine. After upgrading to 10.6, neither scanner-initiated or scanning from MP Navigator EX works with the firewall enabled. The firewall lists exceptions for three applications: Canon IJ Network Scan Utility.app Canon IJ Network Scanner Selector.app MP Navigator EX 1.0.app I get no further blocked warnings, and /var/log/appfirewall.log lists nothing for today (my latest attempt to use it).

• Make Mac OS X mouse acceleration more Windows-like

  - by TomA

  The mouse acceleration on Mac OS X is driving me nuts. It may work for touchpads but nothing beats the Windows' acceleration curves. Is there a way to modify the behaviour on OS X? I tried getting a Microsoft mouse driver for OS X but it didn't work since my mouse is not from Microsoft.

• Set resolution of unattached display in OS X?

  - by Brad

  I have an HDTV that I'm hooking up via DVI to HDMI from my Mac mini. In my struggle to eliminate overscan I managed to set the screen resolution to something not supported by the tv. How do I change the resolution without that screen attached? Specifically my tv says it's "720p and 1366 x 768 Resolution". The 720p resolution option in OS X made for a ton of overscan (couldn't see menubar or dock at all). So I tried something x 768 and managed to shoot myself in the foot with an unsupported resolution. I thought it was okay to experiment since a resolution change times out if you don't accept it. Apparently that didn't happen for some reason. I've already deleted the com.apple.windowserver.plist in /Library/Preferences as I saw suggested in other places, with no effect.

• Adobe Illustrator - Objects are Expanded on Restart

  - by Shatou Dev

  I use Adobe Illustrator extensively for mobile development. For example, for Android app, I have many illustrations with different densities and sizes. I use many effects such as outer glow, round corners and such. However, sometimes, when I close the .ai file and re-open it later, I found all my objects expanded. Effects are expanded. For example, the round corner effect is now expanded and I cannot re-size any object. I am using a MacBook Pro. I am suspecting both Time Machine and Dropbox. As much as I can recall, it also appears with CS6 version, not CS5.

• Can't use command line – "command not found" after editing PATH

  - by MEM

  I'm running OS X Mavericks and was trying to install MAMP PRO 2.2. I was trying to configure the PATH variable to have the PHP binaries of MAMP PRO. I added the following line on my ~/.bash_profile file: export PATH=/Applications/MAMP PRO/bin/php/php5.5.3/bin:$PATH As you may notice, since I have MAMP PRO and not just MAMP, I've added a space. As a consequence, I know have the following error each time I run the terminal: -bash: export: `PRO/bin/php/php5.5.3/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin': not a valid identifier Worst: I can't get any command to run, like: ls, clear etc. I always get: "command not found" I don't even know the absolute path for ls. How can I make the commands work again, so that I can properly fix the path I was trying to setup on the .bash_profile file?

• Spreadsheet application that can handle big data OS X

  - by Peter

  I've been working with Excel for quite a while for some statistical analysis that I do regularly. The size of the data that I'm working with has gotten much larger as of late, however. The layout of the databases in question is quite simple, usually just three rows which includes a UNIX timestamp, and EST value, a proprietary numeric value and finally an average of the rows that have a timestamp +/- 1000 that row's timestamp (little AVERAGEIFS() formula). That formula and the EST conversion are the only formulas in the sheet. I'm beginning to work with files with 500,000+ rows. Running the average formula down the entire row takes forever. The end result is the production of print-worthy graphs. I'm looking for either a UNIX CL utility or separate spreadsheet/database application that can handle this amount of data without melting my CPU or making me wait an hour. Is there anything out there? TL;DR: Simple excel sheet with over half a million rows is getting too slow to work with. OS X alternatives?

• Different buddy lists for different accounts in iChat

  - by Idlecool

  I have currently 4 accounts added to iChat, Standard GTalk GTalk For Google Apps Facebook Olark Facebook and Olark have their own Buddy List Group viz. Facebook and WebUser groups and thus those buddies come in a separate list, while the buddies from GTalk and GTalk from Google Apps do not have any group associated with them and they come under Buddies list. It's a bit of a pain because I want to have buddies from GTalk for Google Apps in a separate buddy list than the default one. Is it possible to do it in iChat?

• How to Suppress Repetition of Warnings That an Application Was Downloaded From the Internet on Mac OS X?

  - by Jonathan Leffler

  On Mac OS X, when I run Firefox (and Thunderbird, and ...) which I downloaded from Mozilla, the OS pops up a warning that the file was downloaded over the internet, giving the date on which it was downloaded. I have no problem with that warning on the first time I use a downloaded application - but the repeated warnings are a nuisance. Is there a way to suppress that dialogue box? Is there a way to avoid it appearing in the first place? (Some applications I download from a corporate intranet - those don't produce the equivalent warning; any idea what the criteria are for when the warning is generated?)

• Different DPI on MacBook Pro and external monitors - what options are there?

  - by Ollie G

  I have an external monitor connected to my MacBook Pro, the two screens have different DPIs. Ideally I would like them to be the same, but as this is not the case, the best option I can see is reducing the resolution of the MBP screen to bring its DPI as close as possible to the external monitor. This introduces scaling artefacts on the screen, as LCDs don't look good at non-native resolutions. Is there a standard or best way of handling this, and if not, what other options are available?

• How to re-map command and option keys on Mac OS X with a PC-keyboard ?

  - by Petruza

  Hi, in my keyboard the command key is mapped to the windows key (I'm using a regular PC keyboard) so I only have a left command, because the space on the right is occupied by the useless Fn key. I've used Ukelele and also edited keyboard mappings but that's for printable characters, doesn't actually allow you to map modifier keys on the keyboard. Thanks!

• Aventail VPN connection doesn't work

  - by Warlax

  I installed the Aventail VPN client on both the Mac and a Windows 7 machine, both on my home network. When I try to connect one or the other (I make sure one is disconnected before connecting through the other machine), I get a connection and view the correct certificate - accept it and Aventail tells me that I am connected. However, accessing any page inside my company's network is only possible on Windows. On the Mac I get this page: It looks like my ISP doesn't know how to redirect me? Maybe something about my DNS being set incorrectly on the Mac? Our helpdesk has been completely useless.
