Apple has removed the last remnants of Intel silicon from its Mac computers. Repair instructions and tools specialist iFixIt recently took one of the newest MacBooks to pieces (an\u00a0M2 processor<\/a>\u00a0model) and discovered that Intel USB4 timer chips on previous generations had been swapped out for another brand.<\/p>\n

\n
As noted by Twitter user\u00a0SkyJuice<\/a>, this component change was spotted in an\u00a0iFixIt\u00a0<\/a>Teardown last week, and it marks a sad milestone for Intel with regard to its Apple relationship. In the zoomed detail motherboard pic, you will notice two chips which carry the codename \u2018U09PY3\u2019. Apparently, previous MacBooks were using Intel’s JHL8040R Retimer chips for USB4 and Thunderbolt support.<\/div>\n<\/div>\n

We don\u2019t know who has made the new U09PY3 USB4 retimer chip, The source indicates it is a custom design, and we can\u2019t get any further information from the markings in the image. Apple hasn\u2019t said anything publicly about this change, and it isn\u2019t expected to. It will have probably changed this chip for supply chain or cost reasons. Another reason behind a switch could be dissatisfaction with the Intel JHL8040R retimer, but again we haven\u2019t heard any mutterings about this.<\/p>\n
