In Photoshop - Preferences - Performance, is the [ ] Use Grahics Processor option selected? If not, can it be?
This feature is available on Intel HD 4000(Ivy Bridge) or just on Nvidia and AMD ? Because on many websites says only on Nvidia and AMD ..
It's supported when the GPU reports to Photoshop it can provide what Photoshop needs. Adobe lists those they have tested toward the bottom of this page:
Near as I can tell, yours is listed.
If you are not able to enable the Use Graphics Processor setting, it's likely because either something's installed that interferes with the driver on your system - or the driver is faulty and needs to be updated. Mac users must get driver updates through Apple with OS updates.
To diagnose the issue further will require a Mac expert, which I am not.
