How to Fix Mac OS X File Permissions for the Entire Home Folder. If all else fails and your home folder is messed up you can try to reset the user’s Home folder permissions and ACLs back to the defaults. After backing up all data on the Mac, proceed at your own risk with the following steps. Ever have a problem on your Mac, where you can’t type the letters and numbers 7, 8, 9, U, I, O, J, K, L, and M—and maybe some others? It’s probably Mouse Keys at play, an accessibility.

For example, the executable file of a macOS app is in the Contents/Mac OS/ directory of its bundle. When running the lipo tool, include the -archs parameter to see the architectures. The following example shows how to use lipo to view the list of architectures for the Mail app in macOS, and the results when Mail is a universal binary. This game is hard, and you will have to die a lot. You will die hundreds of times, but the sense of accomplishment is much bigger because of it. Super Meat Boy actually evokes fond memories of times when games were hard. The game offers more than 300 levels, all filled with traps like fans, rockets, lava pits, and other things designed to crush. To transfer content using Smart Switch for Mac, you will need: 1) A Samsung mobile device with Android OS version 4.3 or later 2) An old device that meets one of the following requirements.

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.

Make sure that your Mac has a connection to the internet. Then turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.

If you're asked to select a user you know the password for, select the user, click Next, then enter their administrator password.

Reinstall macOS

Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions.

Follow these guidelines during installation:

• If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
• If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
• If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
• Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.

After installation is complete, your Mac might restart to a setup assistant. If you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.

Other macOS installation options

When you install macOS from Recovery, you get the current version of the most recently installed macOS, with some exceptions:

• On an Intel-based Mac: If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
• If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. If you just erased your entire startup disk, you may be offered only the macOS that came with your Mac, or the closest version still available.

You can also use these methods to install macOS, if the macOS is compatible with your Mac:

• Use the App Store to download and install the latest macOS.
• Use the App Store or a web browser to download and install an earlier macOS.
• Use a USB flash drive or other secondary volume to create a bootable installer.

It’s true that MFS didn’t have folders—but it was also superseded by HFS all the way back in 1985! From my research, there’s only one generation of Macintosh computers (the original 128K and 512K) that did not ship with HFS. MFS was standard for a very short period of time.

The article hints at how files work. On MFS you would refer to a file as a (volume ID, filename) pair. On HFS, you would refer to a file as a (volume ID, directory ID, filename) triplet. A bunch of toolbox calls (syscalls) got duplicate versions for HFS—but if you were working with legacy code, you could create a fake volume ID called a “working directory” that could be used as if it were a volume ID in a (volume ID, filename) pair. These “working directories” are just awful. The working directory table is global to the entire system and they are not reference-counted—if you open the same working directory twice, you get the same ID both times, and you only have to close it once.

As a funny note—the original filesystem, MFS, had a maximum file name length of 255 characters. HFS, its successor, had a 31-character limit when it first appeared. As a compromise, the new FSSpec file APIs that appeared in System 7 used a 63-character limit filename, because 63 characters was the maximum filename length that the Finder supported.

You could create files with names longer than 63 characters on MFS volumes, it’s just that if you browsed these volumes in the Finder, the Finder would crash!

I’ve got a blog post in the work that is going through some of the wackiness I’ve seen in the old Mac OS filesystem API, and I’ve recently been on the RetroDev Discord helping some people write file handling code for classic Mac OS programs.
