Technicians in bd a have reportedly succeeded in upgrading the memory and storage of the M1 chip, suggesting that Apple's integrated custom silicon for the Mac may be more flexible than previously thought.
Reports of maintenance technicians being able to expand the memory and storage of M1 Macs began circulating on Chinese social media over the weekend, but now international reports have started to clarify the situation.
Technicians in Guangzhou, China have discovered that it is possible to detach the RAM from the M1 chip and its nearby SSD module and replace them with larger capacity components, which are correctly recognized by macOS, without breaking the device.
As proof, a large number of images showing the process of a base model M1 MacBook Air with 8GB of RAM and 256GB of storage being upgraded to 16GB of RAM and 1TB of storage, and this change being correctly shown in macOS Big Sur, have been shared online
The RAM and SSD components on Apple's M1 Macs are soldered in place, making the procedure extremely challenging, and there is reportedly a high chance of failure. This invasive unofficial upgrade also undoubtedly breaches Apple's warranty.
