My CPU is Core 2 Duo 8500. 2 gb ddr3. Some things are slightly newer on my machine. It is a legacy Asus system as well. My guess is, if it worked at your machine, it should work in mine too. So, you booted Mojave in Safe Mode. Did it allowed for Clover and FakeSMC to be installed and to boot from them? Was audio working?I had a core 2 duo E7500, 120 gb ssd (with hfs as the file system), 4 gb DDR2 Ram @ 667 mhz, and it has an asus motherboard with a legacy bios (I can’t remember the exact model number). I was using a 9400 gt 512mb for High Serria. But I temporarily installed a evga gtx 760 4gb for Mojave. For a long term graphics solution I plan to use a gt 610 since I only use this computer for Xcode. As far as I know a gt 610 is metal supported.
