    My Laptop is running slow since the update, Was nice and fast since I had modem upgraded to 400 mbps. Do u think if I do clean install would help the slowness. If I do Can I use Journal and Guid in setting before format rather than APFS and Guid ?? I ve done Onyx and clean up doesn't make any difference..I have High Sierra 10.13.6
    Thank You
    Thanks in Advance

    When you (re)install High Sierra, it will automatically convert SSD drives to APFS. And all retina MBP models have SSD drives. So it doesn't matter what you format/partition it as beforehand.

    Before you attempt anything, see these hints;

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    I put it in safe mode and did Disk Ultlity, found hard drive was corrupted ( yellow triangle ), was advised to do Disk Utility in Recovery mode so I did and was going to reinstall High Sierra then said. nah, I restarted back to normal and went thru web much. faster like back to what I had... Going to see if it good for few days, if not then maybe restore H/S...Do u think restore H/S might do if need to?
    Thanks in Advance

    If it's working fine and it sounds like DU fixed the problem, why expose your SSD to excessive wear and tear with a complete restore??

    Just carry on...

    @Ron:

    You need to take it seriously whenever your drive needs repair. SSDs can fail without notice so be sure to backup your data daily. Use CCC and Time Machine to make sure.

    Comcast Tech was here and found my modem setting was screwed up, wrong password, 8 to 10 updates not doing its job and its back log... He reset it to factory setting and catch up on updates that takes more than hour. Bingo runs fast and getting avg 480 Mbps...
    Happy now...
    Thanks in Advance
