Although everything is working fine with my Macbook Air from Mid-2013, I have a few errors that bother me.
Here they are:
Onyx says this:
The SMART status was not verified because it is not supported by this hard disk.
But the system report writes this:
disk0s2: Media Name: APPLE SSD SD0256F Media Size: 250,14 GB (250 140 434 432 bytes) Medium Type: SSD Protocol: PCI Internal: Yes Partition Map Type: GPT (GUID Partition Table) Status: Online S.M.A.R.T. Status: Verified PV UUID: 4F6EBACC-CA60-4DE6-95BF-37F42D820284
After installing smartmontools:
smartctl disk1 -a SMART support is: Available - device has SMART capability. SMART support is: Enabled === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED
So SMART seems good, maybe onyx is in fault. But my cksum mismatch problem is still here
When I run disk utility and I perform a verification on my hard drive I always get this:
Invalid Disk Label @ 250123653120: cksum mismatch
And sometimes if I wait enough time (a few days) after a repair (with the cmd+R on boot utility) I get this kind of error: Incorrect block count for file (...)
This last problem seems to happen with files I downloaded and most likely which I didn't finish to download.
What I think:
When Yosemite came out I installed it, but since I found that even resizing a window wasn't as smooth as on Mavericks I decided to downgrade using my Time Machine backup.
Do you think upgrading back to Yosemite would fix all this? And would I still find this kind of performance?
Edit: If it is a good idea, I have no problem with doing a clean install of Yosemite.
Thanks in advance for your help. My Mac is still young and I don't want him to be sick.
