I heard that it was the day ENIAC was revealed to the world: The completed machine was announced to the public the evening of February 14, 1946 and formally dedicated the next day at the University of Pennsylvania The theory being that there were no "files" in existence prior to that date. With regard to the time, 0x4F3AFDB0 (from Finder.h above) mod ...

I can confirm (from second-hand bad experience & first-hand testing) that a complete disk erase & clean reinstall does not disable Find My Mac. You need to also either: Reset the Mac's PRAM (aka NVRAM aka firmware settings). You can do this by holding Command-Option-P-R at startup, and holding them down until the computer has restarted & chimed ...

No is the simple answer. The Mac UI is based on the premise of the application menu always being at the top. The reasoning was that you just have to move the mouse to the top of the screen to ensure you were at the menu, no hunting to find the menu bar on a window that could be anywhere on the screen. This has been the case since the beginning of Mac OS in ...

Apple’s EULA states that you’re only allowed to install OS X on Apple hardware. If it’s legal to go against an EULA depends on the country and its legislative authority.

I would do a full wipe on any new computer I bought anyway, regardless of iCloud. Regardless of that - Before buying it, I would want to see it turned on and working. Then have the seller go into iCloud preferences and turn off everything, then log out of iCloud on the machine. Basically, have them follow this: ...

The only way I've ever seen this done on OS X is via the Fluid app. Fluid is just a WebKit wrapper around a specific URL and without the browser navigation tidbits in the windowing. It presents the website as an "app" but it's still running in a browser window, albeit one with fewer decorations. Fluid lets you create a Real Mac App (or "Fluid App") out ...

Typically, an application will offer a way to both close the UI and quit the application. These are usually standardized to command ⌘+W to close the UI/window and command ⌘+Q to quit the application. Some applications will still quit entirely when you use command ⌘+W, such as Preview. You can usually rely on this shortcut to close the window without ...

George Garside's path is correct. Latest JDK released today from Oracle. I advise downloading directly from Oracle's Site. Use the symlink to create your JAVA_HOME variable. Add the following to your .bash_profile or .bashrc profile. export JAVA_HOME=$(/usr/libexec/java_home) Just downloaded the kit and added the above to my .bash_profile. As you can ...

The first Used/Available/Capacity is the obvious "How much of my 1 TB drive is full?" measure. The second tracks internal storage structure called an inode or index node. On traditional UNIX filesystems, there were a fixed number of inodes which are used to track files and directory entries (metadata and filesystem implementation data). When you ran out of ...

You always have the option to hide the active program. When the application in question is active (in front of all others) there are 2 options: option ⌥+click on the Desktop command ⌘+h The first option always works or at least I can't think of any exceptions this minute. The second is supported by most applications. In either case: Your session will ...

Yes, it's possible, but that doesn't mean you should do it. Finder/etc doesn't stop you deleting it, and it's not a 'system' directory (despite being created by the system), but is it causing a problem, enough that you want to delete it? Apps can depend on that directory and deleting it could cause problems, now or in the future. I don't have any examples ...

Place a foot in the door. On each of your disks, create a text file, open it in TextEdit, add some line, and leave the file open unsaved. I think this trick will prevent ejection. Test this trick, try to eject the disk and come here tell us the result. This trick can easily be automated.

An updated answer for Lion and above: You can also type ^ ⌘ <space> to bring up the characters menu, then start typing to search, and search for place of interest, then press enter to start selecting them, then tab to the correct result, then enter again to insert it. Sounds like a lot, but it can really be narrowed down to ^ ⌘ <space> pla ...

App Store is for acquiring OS X software and alike, while iTunes is for acquiring iOS apps and everything media-related (music, movies, podcasts, etc.). Although they are separate applications, the App Store application must be relying on the iTunes "engine" for some functionalities.

.zshrc is a file run when you start an interactive zsh shell, found in your home directory. The error message says you have an export command which is written incorrectly on line 48. not valid in this context means you're trying to export something that's not a variable. It looks like you're trying to add stuff to your PATH, but are substituting the current ...

XQuartz is the continuation to Apple's depreciated X11.app which used to be part of OS X: X11 is no longer included with OS X, but X11 server and client libraries for OS X are available from the XQuartz project: http://xquartz.macosforge.org. You should use the latest available version of XQuartz. Source: http://support.apple.com/kb/HT5293 X11 is a ...

The Mac hardware stores the boot volume in NVRAM so you could power off the computer and then reset things by holding the Command Option P R keys down. Once you've heard two boot chimes you can release things and if the Mac OS X volume is viable it will boot first. If that doesn't work then it's likely that the OS X volume has issues and the system is ...

But there is also ipfw, a packet filtering firewall like netfilter/iptables on GNU/Linux. It can either configured using the command line, or using a graphical frontend like the free/libre Icefloor.

You can use Keyboard Maestro with a macro such as this which takes the current clipboard and inserts its contents by typing it rather than pasting, allowing the clipboard to be entered into fields where pasting is forbidden.          Also, for what it's worth, OS X 10.10 Yosemite does let you paste into the ...
