In hindsight, I’m not sure why, but I upgraded my fantastic 11″ MacBook Air from 10.6 to 10.7 the day that Lion was released.
At first, I liked the changes. I still think that Mission Control is a nice improvement over Spaces and Expose, but otherwise, there aren’t many compelling new features for me in 10.7. Still, change is inevitable, so I may as well get used to the backwards scrolling, the noticeable drop in performance, and all of the other new changes, or so I thought until I started using 10.7 day-to-day.
Since August, I have been using 10.7 on a 24″ iMac, my 11″ MacBook Air, a 24″ iMac at work, and a 15″ MacBook Pro at work. It’s been more or less fine on all machines except the MacBook Air, which is the one I use the most.
On the Air, I’ve had spotty WiFi behaviour where it had been perfect previously, the occasional lock-up, and most alarmingly, it was through it that I learned of Preview and Finder’s new bad behaviour in 10.7.
Try this on a 10.6 machine:
- Make a directory
- Drop 20 images in
- Name them in order: 1.jpg, 2.jpg, 3.pdf, 4.png etc.
- Highlight them all
- Open them in preview.
