MacBook Pro models from late 2008 are experiencing sleep mode issues following the latest firmware update, version 1711. After the update, when the Mac is put into sleep mode, it wakes up after a few seconds. This problem is not prevalent in all models, only those using the Crucial M4 SSD.

Users have attempted various solutions, including resetting the system management controller (SMC) and the PRAM, but to no avail. The issue persists even after reformatting the hard drive and reinstalling the operating system.

Crucial’s technical support has acknowledged the issue and is working on a solution. They’ve suggested a temporary workaround: users can revert to the previous firmware version, 070H, until a fix is released. Users who have already upgraded to the problematic version can find the 070H firmware on Crucial’s website.

Despite this, several users have expressed disappointment with the situation, particularly as the sleep mode issue can lead to battery drain. They’re eagerly awaiting a permanent fix from Crucial.

It’s important to note that this is not an issue with the MacBook Pro itself, but rather a compatibility issue between the MacBook Pro (late 2008) and the latest firmware version for the Crucial M4 SSD.
