Apple Releases MainStage 2.2.1 and MacBook Pro EFI 2.8

Earlier today, Apple released an update to their MainStage 2 app that accompanies the Logic digital audio workstation. This update resolves a total of sixteen issues within the live performance app and it is recommended that you update promptly if you wish these bugs. Sadly, this update is only available to users who have purchased the app through the Mac App Store when version 2.2 was released back in December of 2011. This means that, should you already own the app by purchasing a physical copy, you will not be allowed to update unless you purchase the MainStage app by itself again first…

The MainStage 2.2.1 update addresses overall stability and performance issues including:

- Resolves several issues related to the download and installation of basic and additional content
- Addresses a stability issue that could cause MainStage to hang during startup while initializing MIDI
- Fixes issues that improve CPU performance and latency, particularly when using the Playback plug-in
- Resolves an issue that prevented stereo audio input from working as expected
- Fixes a problem that blocked sidechain input for plug-ins

Additional details on the MainStage 2.2.1 update are available on Apple’s support page. MainStage 2.2.1 costs $29.99, which isn’t too bad considering the feature upgrade that’s offered.

Apple has also released an update for MacBook Pro EFI Firmware on the late 2008 15-inch model, bring it to version 2.8. The update fixes a graphics issue that may cause the notebook’s display to flicker and it is recommended that you update as soon as possible. You can find the update in Software Update or directly download it on the support page.

This update is recommended for MacBook Pro (15-inch, late 2008) models. The update resolves a graphics issue that may cause the internal display to flicker.

Just last week, Apple updated the EFI firmware on their Mac mini (mid 2011), iMac (early 2011), MacBook Air (mid 2011), and MacBook Pro (early and late 2011). The updates improved the stability of starting the computer from the network and also resolved some issues with HDCP and USB storage.
