I installed Mavericks over Mountain Lion on a MacBook Air early 2011. Let’s first start with the good stuff I found so far:
- More disk space. Before the installation I had 22GB free and now I have 34GB free. I have no idea what stuff was occupying 10GB of space, anyway it’s gone!
- Faster! Yes surprisingly it’s faster than Mountain Lion and Lion. I was a little bit afraid about the speed, specially after seeing how bad iOS 7 is doing on the iPhone 4 and the iPad 2.
- All my important apps work. So far I tried: TrueCrypt, VirtualBox, Chicken, Google Earth, LightRoom, Photoshop CS4, Illustrator CS4, AptanaStudio 3, Libre Office, TextWrangler, Audacity, VLC, JEDict, CyberDuck, Skype, go2Shell, Temperature Gauge.
- Leap Motion drivers work.
- Full screen works as indicated by Apple. I finally have my top bar enabled on the second monitor so I can now work full screen without sacrificing one monitor. I had one pretty bad issue that will be explained later in the post.
- The american voice Samantha is sexier than before.
- Disk utility didn’t crash until now…
- Battery had a better performance. I didn’t measure the charge time, but it discharges at a slower pace.
- I can’t rotate the second monitor. I used it at 90 degrees rotation but I can’t use it now. It was very handy specially to see the iPad/iPhone simulator working on it… Look at the image. This is ridiculous:
- When I activated the second monitor in LightRoom it worked fine. But the second one’s top bar overlapped the maximized Lightroom’s second view. I can adjust that by making the second view a window but there should be no overlap of the content.
- Sometimes you get something like this. I was in the launchpad and the app behind got an alert. The mouse pointer was operative with the launchpad icons but the content of the program overlapped the launchpad view. I had to click outside the window to get rid off the launchpad and respond to the message. If this is not a bug, it’s poor design
- In Lightroom I don’t get the right colors on the controls. Look at the image on the left is from Lightroom running on Mountain Lion and the right one on Mavericks. Don’t you see something is missing?
- I also had an issue with the keyboards. I have a Japanese keyboard which I use most of the time. I also installed an Italian and Spanish keyboard when I have to write in those languages. The problem is that the Japanese keyboard, when is set to Romaji, it means to write in roman characters, thinks that the previous used keyboard is the default romaji. So I ended up with a Spanish keyboard when I want to use the Japanese distribution. This didn’t happen with Mountain Lion. I fixed it by installing the US keyboard which maps the Japanese one. This is conceptually wrong, because based with the previous schema, the US keyboard should match an US keyboard distribution instead the Japanese one. Finally I gave up all the keyboards and I followed the advice of my friend @rcivit Now I use shortcuts to create characters like éáñ and so forth. Anyway I still have to install the US keyboard on a Japanese keyboard to have the right mapping…
So far so good, I won’t rollback to Mountain Lion mainly because Mavericks seems faster and more battery friendly. Anyway I wouldn’t use it for your production machine after at least 5 or 6 months.
