I'm having problems with Adobe CC 2015 Photoshop crashing on OS X Yosemite and I'm trying to determine if it's the driver that Apple installed.
System Information indicates this:
ATI Radeon HD 4870:
Chipset Model: ATI Radeon HD 4870
PCIe Lane Width: x16
VRAM (Total): 512 MB
Vendor: ATI (0x1002)
Device ID: 0x9440
Revision ID: 0x0000
ROM Revision: 113-B7710C-176
EFI Driver Version: 01.00.318
Is there a newer driver for this OS? I can't seem to find any drivers for this graphics card on OS X Yosemite, or any Mac OS, for that matter.
