I've never installed an OS on its debut. I generally wait 5-6 months for the .4 release.
This time was different. I really don't like Lion (Apple removed it rather quickly from the App Store, didn't they?). I also have a MacBook Air that I really don't rely on -- so I could sacrifice it.
Notes so far ...
- I backed up the installer prior to installation. (I did the same thing for Lion. Glad I did since it's now gone from the App Store. I'll have it if someone needs it.)
- In addition to the 4+GB installer there were GB or so of iWork and iLife and firmware updates to apply.
- The Guest account was reenabled. I removed it.
- I was able to add a keyboard shortcut of cmd-opt-S for Save As... (instead of cmd-opt-shift-S). It's good to have Save As back. I also changed Settings:General so I'm asked if I want to save changes on exit (I may change it back to default).
- Unsurprisingly, my broken iCloud Contacts database (hundreds of replicated groups) is still broken. Contacts sucks less than it did though.
- It doesn't feel any faster or slower than Lion.
- I'd read Notational Velocity didn't work. Works fine for me. I run as a non-admin user fwiw. Sync to SimpleNote worked to. That's a relief.
- There's supposed to be a LaunchBar bug with Contacts, but mine was fine. I have iCloud disabled so maybe that helps.
- My Time Capsule backup was gone after the upgrade. Good thing I wasn't relying on it. When I ran TM it showed no backups. I used the option-click trick to get TM to validate my backup and now the backups are all accessible through Time Capsule. I think this may be related to the 7.6.1 firmware bug with older Time Capsules.
- I enabled voice dictation; that's not automatic. (Lately it's working on my iPhone, but I doubt it works as well on the desktop. Unrelated to this, but Siri is actually working again.)
- None of my apps were moved into an 'incompatible application folder'. This machine has always run Lion, so that's not surprising.
- Chrome seems fine, I'd heard it had problems. Maybe Google fixed 'em. I had to make it my default browser again.
- There are new Parental Controls for the Game Center. I didn't see any other changes there.
- I think I'll like Messages. It does remind me though that I'm going to have to come up with some way to fix my broken iCloud account. I don't think Apple will be much help.
- What's with Video Chat being in both Messages and FaceTime? Isn't that a bit odd?
- I like the unification of App Store and system updates.
- For kicks I tried using Google's m.google.com ActiveSync service as an Exchange Account. Didn't work - couldn't contact server.
Overall it feels like a less broken version of Lion. Maybe I'll upgrade my main machine in September rather than February.
