  • Steps to diagnose performance bottlenecks on Mac OS X

    - by Dave Cahill
    If you wanted to track down performance issues on a machine running Mac OS X and find out what was causing slowdowns, which command-line or graphical tools would you use, and how would you use them? I'm interested in advice on the best tools, and explanations of how to use them - when a machine slows down or freezes up, I'd like to be able to dig down and understand what's going on, memory / disk / CPU-wise. Thanks.

  • Where does the information shown by OS X Terminal 'Display all commands' feature come from?

    - by Sergio Acosta
    I just learned that if you hit and hold ESC while on the Mac Terminal, a prompt appears after a few seconds offering to show every command available on your system, including aliases, built-ins, and executables on your PATH. Soruce: http://www.mactricksandtips.com/2008/05/list-all-possible-terminal-commands.html However, the output is show through a more filter, and I cannot grep it or pipe it to another command. Does anyone know how this magic output is generated? Is it just generated on the fly by Terminal? Is there a bash command that can be called explicitly on the command line and get the same result? It is mostly curiosity, but I would love to be able to get the results as text I can post-process and not just browse on screen.

  • Canadian English on Apple products

    - by thepurplepixel
    Apple is an American company. As many of you probably know, Canadian English is different from American English, and closer to British English (e.g. colour instead of color). I use iWork and Microsoft Office for Mac (along with many other applications on OS X), and OS X, nor my iPhone, have an option to switch to Canadian English. Yes, you can select Canadian English as an input language in the language bar, but any program that uses the central OS X spell checking (from Mail to Office to iWork to Chrome) will check words against an American English dictionary. I know asking a question that involves an iPhone component is borderline off-topic, but I know on my iPhone I can select British English, but that turns my $ into £ and has a few other weird spelling quirks. Simple question: Is it possible to make OS X (and maybe the iPhone) use a Canadian English dictionary for its spell checking? Because British English just doesn't cut it anymore. Thanks!

  • How to properly store dotfiles in a centralized git repository

    - by asmeurer
    I'd like to put all my dotfiles (like .profile, .gitconfig, etc.) in a central git repository, so I can more easily keep track of the changes. I did this, but I would like to know how to properly handle keeping them in sync with the actual ones in ~/. I thought that you could just hard link the two using ln, but this does not seem to work as I expected, i.e., if I edit one file, the other does not change. Maybe I misused the ln command, or else I misunderstand how hard links work. How do people usually do this? Judging by GitHub, it's a pretty popular thing to do, so surely there's a seamless way to do it that someone has come up with. By the way, I'm on Mac OS X 10.6.

  • How to create a bootable Ubuntu Linux (10.04) USB installation for Macintosh

    - by vdavidovski
    I tried searching the Internet, but could not find a decent tutorial explaining how to create a bootable Ubuntu Linux (10.04) USB installation that could be run not only on a PC but also on Macs and MacBook Pros. In addition, I tried refit, but ended with "Missing operating system" error. Here is basically the layout of my bootable under PC Ubuntu USB drive (using MBR): Partition 1 (ext3, bootable) - Ubuntu Linux 32 bit, contains also grub2 bootloader. Partition 2 (ext3) - Ubuntu Linux 64 bit. Partition 3 (fat32) - contains data. What would be the best way to enable this drive to boot under Mac OS X? And if refit has to be used, could I simply have one more partition on the USB drive containing it? Thanks!

  • What's the fastest way to store/access large files?

    - by philfreo
    I do a lot of video editing on my Mac and need a way to store very large (30 GB) files, and don't have room on my HD. A USB/Firewire external hard drive would work, but it seems way too slow for consistently working with such large files. I've also considered buying another computer, with a large hard drive, and putting it on the same network with a shared folder. What's the fastest / most efficient way to do this? Please consider USB 2.0 speeds, hard drive read times, ethernet speeds, etc. Are there other options I should consider?

  • How to determine if a file has been backed up?

    - by Console
    I try to consolidate old drives to new ones of larger capacity. Sometimes files have been renamed, but are otherwise identical. Sometimes an old directory has just a few more files in it than a newer directory with the same name. Sometimes a file has the same name but the size differs. So I often find myself asking the question: Are there any files on this old drive or directory that I haven't already copied to the new drive? I just want to know that I have the files, I don't want to try and sync stuff automatically (Syncing tools tend to just sync, creating duplicate folder structures and other problems, so I prefer to do it by hand). Basically, if an old drive has a file called "foo.bar" ten directories deep, and my new big drive has an identical file called "oldstuff.zip" in the root, I just want a "yes you have it" or "no, unique files exist". Is there a free tool, a script or a quick and easy method (Mac/Unix or Windows) to get the answer?

  • Accidentally deleted /opt/local/bin without backup. Any help?

    - by Aaron
    Hi all, I'm on a Mac OS X 10.5.8 I was recently uninstalling mysql5 from /opt/local/bin. I typed: rm -rf /opt/local/bin mysql* instead of rm -rf /opt/local/bin/mysql* This deleted my entire /opt/local/bin directory which puts me in a bit of a bind. Is there any way to recover these files? If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folder? If I end up needing to re-install everything in this folder, what is the best way to go about doing this? Thanks in advance!

  • Truecrypt in place decryption. Is this possible?

    - by Keyo
    I want to decrypt my entire partition and turn it back into standard NTFS. I encrypted a large partition on my 1TB drive before I took it through the airport. For this I used the in place method on truecrypt for win7. I'm on a mac now and there doesn't seem to be any way to decryppt the drive in place. It mounts fine, but I don't want to buy another drive just so I can shift files around. The drive is hooked up via USB. Would this be a problem?

  • Macbook Pro + Windows 7 (bootcamp) = Terrible battery life

    - by Scott Beeson
    I recently put Windows 7 Ultimate x64 on my wife's Macbook pro because of some software she bought for her business. Since then, the battery life has been abysmal. I've identified and researched one of the problems, which is display brightness. There is no brightness control in the windows power options, but I did manually turn it down in Bootcamp. However, it is still reporting very low battery life estimates. I'm wondering if this is because Windows thinks the display is at full brightness. Can anyone shed any light on this? (Pun intended). Also, are there any other things to look out for that may improve the battery life? (I mean in the context of Mac + Windows, not in general)

  • How to share iPhoto library between multiple users

    - by Mark
    I am looking for advice on the best way to share an iPhoto library between two users on the same Mac. I currently use this approach and it works fine most of the time. One issue I have is that I will get a permission error when syncing my iPod. This seems to happen if the other user has used iPhoto and I have not opened iPhoto before syncing the iPod. If I open iPhoto then sync the iPod again there is no error. How do others solve this problem?

  • Have you considered switch from Windows to OS X?

    - by Oscar Reyes
    For several years I wanted to move from Windows to OSX. Mainly because back then Windows95/98/2000 were terrible options. Now I have finally put my hands on this. Just when Vista and Win7 seems to redeem all the mistakes from their predecessors. The most terrible rant is the lack of the following keys: PageUp, PageDown, Home, End, Supr Not having those made my first programming day terrible on OSX. I don't regret switching, but somehow I expected something else. So: Have you considered switch to mac? What has stopped you? What is holding you back? If you have switched already, are you willing to comeback? (Now I run XP/Vista/Ubuntu/OSX in the same machine, yeah!!)

  • Can't access files on external drive after reformatting Macbook Pro

    - by Peter Wells
    I recently had to reformat my Macbook Pro, and imported my account and settings from Time Machine via the Migration Assistant. Everything on the Mac itself is fine, but now I don't have permission to access almost everything on my external drive. A number of folders have the little red 'no access' sign on them and I can't rename or move anything. Looking at the info for these files, it appears that access rights were attached only to my old user account. Is there some way to reassign these files and folders to my new user account? Thanks.
