Tengo MacBook Pro 6,2 mid-2010 de 15 pulgadas con Core i7 2.66GHz, 8GB Ram, 240GB SSD. Desde que no es compatible con un sistema operativo posterior a High Sierra se convirtió en inútil y quería usar Linux en él, pero antes de ir con Linux tuve algunos problemas como la congelación, etc. Y experimenté los mismos problemas en Linux también, así que decidí ejecutar AHT y me encontré con un error de memoria que es 'Failure Code: 4MEM/66/40000000: 0xa50c6e18'
ERROR: 
RAMs: 
No estoy seguro de qué hacer, porque no está claro qué RAM o Slot (tal vez placa lógica) está defectuoso, quiero usar este dispositivo porque todavía vale la pena, es una víctima de la Obsolescencia Planificada. Ubuntu 22.04 LTS y Win10 todavía funcionan en él.
Aquí está el Recuerde Resultado de la prueba.
