This article was written in reponse to Lion, but it applies to pretty much any OS upgrade, aside from the OS X specific apps mentioned.
- Check you critical apps and anything you just can’t do without for compatibility. (Note: Rosetta is gone! you won’t be able to run PPC Apps)
- Update the Apps that you can.
- Purchase Lion from the App store for $30
- Make a USB stick installer out of because the Lion installer self destructs (kind of) after the install: http://osxdaily.com/2011/08/02/easy-way-to-make-lion-install-disk/
- Backup your files (or better clone your system to an external HD)
- Run Disk Utlities and Repair the Disk then Repair Permissions
- If you’re really careful, run a hardware diagnostic on your machine.
- Run the installer.
- Open the General preferences and check every pane for changes and make adjustments. (for instance you might want to uncheck “Natural Scrolling” in the Trackpad pane if you like the old way to scroll.)
- Write a terse but well argued letter to Apple about the changes your don’t like.
- Enjoy your new OS. And Check out my review of Lion in case you haven’t already. (Which I must update with my Apple app moving trick….)
So, I’ve had Lion installed for less than a week and there’s some good/great things about it and some really frustrating changes. Now, there’s a lot of articles that cover the same ground and mention the same problems or improvements. I’m going to try to add new information about Lion’s new capabilities and steps backwards. To qualify my statements, let me give you a bit of my background. (Below the main article due to length.*)
Pros: Snappier Performance, Resume on relaunch after quit, Graphic changes/improvements, Finder Toolbar additions, Window resize from any edge, Focus shortcuts, Spelling/Thesaurus/Wikipedia popup, Mail link HTML preview/popup, iCal feature additions, Address Book feature additions, Safari downloads popup and rendering boost, Quicklook improvements.
Cons: Apple applications are immovable, App folder requires admin privileges to move applications, Launchpad not easily organizable & limited configurability, Library hidden by default. Mail lost its “bounce” feature. iCal “hard lock” crash wasn’t easily fixed.
Bottom Line: The improvements to the UI and new features and customizability make for not only a more pleasurable experience that also allows you to save time with fewer clicks and faster responses. The Cons are easily outweighed by the Pros list, and $29 or $69 makes it an even more compelling upgrade.
