There apparently is a communication problem with OS 10.7.5 when I attempt to calibrate my NEC display using the SpectraView II software. According to NEC, Apple has been aware of the problem & will hopefully resolve it in a subsequent OS update. But since the wait has been 3 months, I am considering installing the previous version of Lion (10.7.4).

 

Is there a seamless way to do this "backward install" without incurring other problems & issues? Thank you for any help. I apprciate it.

    If you retained a copy of the 10.7.4 or earlier full installer, just install over 10.7.5. If not, get a copy from one of your friends or associates. If not, you're out of luck, since the ill-designed full installer, deletes itself during installation.

    Most likely it would update directly to 10.7.5.

    No likely about it. That's the only version available.

    You could try the iMac's SL install disc or just buy an universal SL install disc from Apple. $20 USD.

    Typically an installer disc supplied with one model Mac will not work with another.  Fo upgrades to another model you have to use a retail installer disc.
