The function ‘CGContextClear’ is obsolete and will be removed in an upcoming update. Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance.

Hi, I got a MBP 13 mid 2012, Processor Speed: 2,5 GHz, Memory: 8 GB, with OS X Yosemite 10.10.2. Fusion Drive

Crucial_CT240M500SSD1:

Capacity: 240,06 GB (240.057.409.536 bytes)

HGST HTS721010A9E630:

I'm having some problems with my iPhoto app. Last night I had to rebuild the database, and this morning I got the following message in the console:

04/03/2015 06:01:09.103 WindowServer[131]: disable_update_timeout: UI updates were forcibly disabled by application "iPhoto" for over 1.00 seconds. Server has re-enabled them.

How can I solve this?
