Occasionally when I start up my Mid-2012 Macbook Pro, I see the following error messages a few moments after logging in:
This happens about every second or third login. After seeing these error messages, I sometimes have trouble using external USB storage - the power lights on the storage devices will come on, but my laptop doesn't seem to recognize and mount the volumes. I'm savvy enough to know what kernel extensions are and what their purpose in the OS is, and I can tell from the kext names that these relate to external mass storage, so that makes sense.
What I don't know, however, is what can be done to fix this error. Has anybody else encountered this problem?
I'd rather not reinstall the OS if I can get away with it, but I will if there's no other solution - maybe something involving
Edit: I may have just solved my own problem: Running a "Repair Permissions" task in Disk Utility results in the following: As you can see, Disk Utility repaired a number of bad permissions in IOStorageFamily and IOSCSIArchitectureModel - we'll see if the error messages stop occurring as a result.
