EXTREMELY SLOW BOOT / START UP - 2 MINUTES AND 19 SECONDS - MACBOOK PRO 15'' Intel Core i7, late 2013, 256GB SSD, 16GB RAM, MOJAVE

Hi Leroy,

thanks for the suggestion! As I said I already run DU and no errors were found... I will do it again...

Regarding CleanMyMac I didn't knew this (when I said constantly, I meant frequently to be more precise, every month a few times, not everyday or week), I will uninstall it and try what you say, hope you are right!

I'll get back with the results!

Thanks!

All My Best,

J.

Hi Leroy,

Done what you said, uninstalled cleanmymac, run DU and gave instructions in recovery mode to reinstall Mojave... after 2 hours the reinstallation process hasn't finished yet, and the computer is stuck for more than one hour in the apple logo with the progress meter nearly concluded but not progressing at all, it stopped completely... is this normal?

how much time does it take?

if the computer stays like this is there any command to reinitiate the process or at least restart / restore to the computer as was??

waiting to hear from you asap

J.

Leroy, thanks for the suggestion, but the first time doing the reinstall the computer froze... so I did everything again, boot on recovery, run DU and FIRST AID and then reinstalled Mac OS X MOJAVE via the menu of the recovery mode. It took 45 minutes approx. made a restart after it finished and everything is the same, it takes 2 minutes and 10 seconds (it is 6 to 9 seconds faster)... still an absurd amount of time...

Any ideas of other suggestions people=? Thanks in advance!!

deggie, did the verbose boot, couldn't quite grasp what's the issue... read something about audio channels.. but the verbose mode showed data only half way through the start up process, then went into the apple logo mode...

getting really frustrated with this... just wanted to know what is going on...

Thanks for the advices!

All My Best

Hi Leroy!

Thanks for the suggestion, I was avoiding such drastic measures, but it seems the last and wiser thing to do in order to understand what is causing this significant booting time...

Currently haven't the time to do it, due to professional compromises using the computer, but as soon as I am done I will have to erase the HD and restore my data from a backup!

Thanks!

Best Regards,

J.

Hi Leroy,

just a final question regarding the TIME MACHINE back up, I don't use it so excuse my ignorance.

If I do a back up with TM and then with a bootable OS MOJAVE USB pen erase my HD, when I restore it does the TM also restores all the authorisations of the currently installed software? or do I have to re-install all my applications?

I need to know this before I decide to go ahead with this procedures!

Thanks in advance!

Best,

J.

not much, why? I will do it and comeback in a moment with the precise answer! thanks for the assistance!! talk to you in a few ;-)

deggie, I was wrong, it takes approximately the same time, it took precisely 2 minutes e 5 seconds.

Any idea of what could be the problem?

Thanks in advance!!!

J.

no I haven't, I will do that then and pay attention where he stalls or takes too long! thanks for the suggestion, deggie! will be back with the results ;-)
