MacBook Pro EFI Firmware Update 1.9
This update is recommended for all 15-inch and 17-inch MacBook Pro mid 2010 models. The update resolves a rare issue that may cause the system to freeze during startup or intermittently stall during operation, and it improves compatibility with external displays.
The MacBook Pro EFI Update will update the EFI firmware on your MacBook Pro. Your computer's power cord must be connected and plugged into a working power source. When your MacBook Pro restarts a gray screen will appear with a status bar to indicate the progress of the update. It will take several minutes for the update to complete. Do not disturb or shut off the power on your MacBook Pro during this update.
installed fine on my mid-2010 15" i7...
Spaces seems more fluent no more jitter. I have had the gfx update installed before today.
I never had a real problem with it before. Full Screening a 1080p youtube causes a short pause still, but nothing more than 2 seconds.
From my understanding this isn't the problem that is addressed...
That "pause" you experience is the Intel HD switching to Nvidia. Seems like a common occurrence.
Actually this is the problem demonstrated. When it goes full screen on 1080p, it switches to the 330m. Thats where the pause comes in.
I have not seen the issues that people seem to be having of "2minute" pauses. Then again, i havent seen much in terms of issues with this box.
umm i don't have any freezing issues on my 17" i7![]()
