Apple released the OS X Lion on Wednesday and we've been reading up on all the new features. If you're ready for the upgrade from the App Store for $29.99, you should get your computer ready for the new OS X. Make sure to follow these steps before you embark on the Lion.
The OS X Lion has over 250 new features. Most updates are functional while others are purely decorative, like the new icons and login screen. If you're eager to get started, here's a short checklist you should consult before you do.
Apple recommended all users to download the Mac OS X v10.6.8 update, which includes general OS fixes and increases stability, compatibility and security. To update the apps you purchased from the Mac App Store, click the "Updates" button in the toolbar. Run a check for all major software updates outside of your Mac store purchases including any external devices your computer is connected to like a printer or scanner.
For freeing up disk space, we like to use DaisyDisk, a tool that scans your disks and portrays your files as interactive maps so you can easily spot which ones are the largest and evaluate how you can free up space. Of course there are a bunch of other tools you can use to clear up your disk like Disk Inventory X, DiskUsage or CleanMyMac.
Check for App Compatibility
Mashable recommends using RoaringApps to consult which programs will work compatibly with Lion. RoaringApps is a community wiki so you can see what others have been saying and share tips to figure out which apps will run smoothly from Snow Leopard to Lion.
Invest in a Magic Mouse
One of the exciting updates Lion brings is multi-gesture navigation, however you won't be able to experience it unless you have a magic mouse or magic trackpad.
And of course, always make sure you back up all your files before you run an update. You can use Time Machine or create a bootable clone for your current hard drive with tools like SuperDuper or Carbon Copy Cloner. Enjoy the Lion!
Lastly, Adobe released a report on which of their products have run into issues with Lion. You can consult their list here.
