    Hi folks! :-D

    Have a listen to Steve Wozniak on the subject of repairs! (https://en.wikipedia.org/wiki/Steve_Wozniak)

    I've opened up a 24 inch iMac and replaced the hard drive. Not a job for
    the faint-hearted! 😅

    What do YOU fix?

    Changed home button on my 4 (and I think Camera)
    Changed home button and some of the ribbon cables at the deepest level (requiring total disassembly like iFixit) on my 5s, changed camera and
    screen on 6s (but kept home button).

    Changed power supply on 2009 mac pro ( required fair amoujt of
    diassembly due to position of connectors).

    Changed the CPU on my 2013 trash can. Required almost total disassembly
    to reach the cpu nestled behind motherboard against heat sink).

    Changed battery and disk on my laptop.


    The one aspect about right to repair is the TouchID system. Encrypting
    o data by the button itself means the CPU can't use the data and only
    pass it onto secure enclave which is the only thing that has the keys to decrypt. When you have a need to protect citizens from their
    government, such measures are needed. Sad, but that is the case with power-hungry police/intel agencies who want power to peek into anyone
    iPhoen.

    The downsize of this is that you need to pair each individual button
    with each indiidual secure enclave. If you let anyone do this, then the protection is moot since anymore can introduce a modified button that
    allows "man in middle" attacks. So when only Apple can do the pairing,
    this does add some security. (but that assumes the 2 letter agencies
    like CIA, NSA, NSO don't have the ability to pair a button to secure
    enclave).

    The other aspect, and this is diue to Samsung,s BBQ starter phones, is
    that the manufacturers have become very weary of liability that their
    phones can cause if the batteries start a fire, so I can understand (but
    not agree) on ensuring battery are only touched by experienced people.

    On the other hand, if you design the phone poperly in first place, it
    become easy to replace battery in a safe way.

    WOW! I've never worked on an iPhone. You must have nimble fingers!
