Upgrading your iMac 5K 2015 to macOS Sequoia
The Late 2015 iMac 5K is a top-tier machine for OCLP. Here is everything you need to know about the upgrade process.
Compatibility and Resources:
- Best OS: macOS Sequoia runs beautifully on this machine. The Skylake CPU and AMD graphics are well-supported.
- Compatibility Chart: You can find the official list of supported models on the Dortania OCLP website under the 'Supported Models' section.
- Fusion Drive vs SSD: Replace it! Opening an A1419 is tricky because the screen is glued, but replacing the Fusion Drive with a 2TB SATA SSD (like a Samsung 870 EVO) will make the Mac feel brand new.
- Video Tutorials: Look for iFixit or OWC videos on YouTube for 'iMac 27-inch 2015 Screen Removal' and 'Hard Drive Replacement'.
Original Question: "iMac (Retina 5K, 27-inch, Late 2015) upgrade"
Hi everyone!
I just found this and wanted to ask if someone had an experience with upgrading the iMac (Retina 5K, 27-inch, Late 2015). The model number is A1419.
What macOS have you tried to upgrade to?
Where can I find the mac to macOS compatibility table/chart?
I have a 2Tb Fusion drive, have you replaced it with SSD? Are there any video tutorials have you used?
TIA
