mojave install macbook pro slow and no internet

I tried reinstalling Mojave in disk recovery mode but the problem persisted. I tried resetting the PRAM and SMC. No change.

I called apple support and we tried to go back to High Sierra (or Sierra which came on the iMac) but the computer could not identify the hard drive and disk repair would not work on the drive.

I went to the apple store. Their initial diagnostics could not find the problem. When trying to install High Sierra, it indicated the hard drive was locked. They tried unmounting and mounting the drive to no avail. They next tried wiping the drive but it did not respond.

So they took the computer overnight to do repairs. They said that there was a problem in the disk formatting. They wiped the disk and installed High Sierra. Fortunately I had a Time Machine backup.

I suspect that we may al have this disk "formatting" problem. Idk how it came to be. They said that I should have no problem going to Mojave now that the disk was wiped and reformatted. But I'm going to wait.

Maybe Apple will release info on this "formatting issue" so that people can fix it before they upgrade.

You have to patch the firmware on the OWC SSDs for Mojave to work. Apple recognizes that they’re not official hardware and it seems they’re creating problems for those without stock drives. If you still have the original SSD, install Mojave on that and then swap. Here are instructions if the firmware patch does not work!:

This is the firmware patch from OWCs site. Make sure this is for your drive.

Good luck man. I had no idea this was an issue with 3rd party drives. It is a pretty big hassle.

Note that this issue on these particular OWC SSDs is because the controller in question erroneously identifies the SSD to the operating system as a rotational (conventional) hard drive rather than as an SSD.

This is not due to a bug in macOS, macOS is treating the device as the type it is being told by the controller it is.

I have to say (politely) you all need to stop giving out bad advice...

Firstly I am the man with the SSD in Question earlier in the thread..

Secondly .. Patching and Aura Pro X with and Auru pro patch is not going to work as they are different drives.

The problem is with software licences not the drive. That issue you are referring to is not specific to the Pro X.

There is no Patcher for a Pro X ..

Thanks .. hope that clears it up for anyone about to try and patch the wrong drive due to Chinese whispers

😉

You cannot categorically (yet) Patch and Aura Pro X

Advising people to patch / rewrite firmware to drives in error is very bad advice .. you need to watch that ..

We are all here to help each other are we not ?

Just to chime in, I have an Early 2016 MacBook that runs fine on High Sierra, but Mojave install:

1) take over an hour

2) Boot up after install is extremely slow

3) Navigating UI after boot is excruciatingly slow

4) I get the "WiFi: No Hardware found" issue

I have reset NVRAM, SMC & have run Apple Diagnostic Tool, which finds no issues. If I roll back to High Sierra, everything works just fine. I have tried to install Mojave 3 times now, but will not attempt it again unless I can get some kind of assurance that I won't be wasting yet more hours only to get a non-functioning machine.

This is way too technical for me. Why is there a push to install Mojave if it clearly is not ready? The App Store said it was compatible with my MacBook Pro, but once installed the whole system (especially anything to do with “finder”, and that’s about everything,) took ages and ages...

Same problem here. I'm pretty bummed and think Apple quality has slipped considerably.

I upgraded my iMac to Mojave and it completely screwed everything up. The WiFi icon now has an X in it and says I have no WiFi installed. And the computer is unusably slow. Everything worked fine before the upgrade.

Here’s what I tried to fix it. Nothing worked.

- Rebooted

- Reset SMC and PRAM/NVRAM

- Rebooted in recovery mode and performed disk first aid, then reinstalled OS

- Went into System Prefs and tried to change network settings. Computer runs hopelessly slow when I do this and doesn’t allow me to make changes.

- Rebooted in Safe Mode, which took almost an hour

- Created a new user to see if that would work better.

None of these actions helped. But when I reboot in recovery mode, the WiFi logo in upper left corner shows its working so I know it’s not a WiFi hardware issue. But when I boot normally, the WiFi status icon shows an X and says WiFi isn’t installed.

Thanks for your suggestion, but I've spent enough time on this. I don't have any kernel extensions, and I reverted back to High Sierra (took a day of my life so I'm quite fed up already and definitely don't plan on spending more time on Mojave for now thank you).

I had exactly the same issue when upgraded my MacBook Pro 15" mid-2014. First, it took quite long to upgrade. Second, my Mac became very unresponsive (every click will take a minute to respond), third there was no internet even though the wifi was on and connected and fourth the computer was overheating and the fans were not revving up.

In my case it turned out it was the version of Little Snitch I had. It was not compatible and for some reason the process will stay forever with 100% CPU usage. There was also a message that something is not compatible with the current kernel. Once I was able to kill that process and download the very latest version of Little Snitch (that apparently had been updated to support Mojave) all was running fine again. No overheating issues and the computer is quite responsive again. Internet connection works fine as well. My only issue at the moment is the when booting, it stays a little longer on the apple loge with the progress bar. it is just like a frozen for a while at two thirds of the progress bar. Then it continues and all is working fine.

My guess is that you may have a resident application that may not be fully compatible with Mojave...

Glad you found out of it, but I don't have Little Snitch or anything like it, and I have read about others who neither have it. But of course, there might be something other causing a similar problem, but I didn't receive any error messages so I am in the blue as to what it could be, so I will continue to sit this one out and wait until they release and update. Hopefully that will work as it should or it will at least give us a hint as to what causes the problem.

Did see somewhere that apple was changing its file format -- it may be that after the install the files have to be formated to their new way.

I believe apple was doing some testing on iphones for conversion - and then taking it back.

Apple is really bad at letting people know what is going on during an upgrade - very sad.

If you can open Activity - look at disk activity - if it is high - that may mean its doing a conversion.

That is sad. Sure there might be bugs but I would expect a supported computer to be... well, supported. All hardware drivers should have been included in the OS. Perhaps you can create a small partition (if you have free space on the internal SSD) and try to do a clean install. If it still does not work you can boot back into your current OS and just delete the new partition.

BTW, did you check in Activity Monitor for any errors? It may give you hint what may be causing the issues...

Good Luck...

Well, I am not desperate:) High Sierra works fine so I am OK with it. I have a 2017 model 27" iMac but it doesn't have a SSD-disk, but I could have made a partition on that to do as you suggested, but after two botched attempts to install Mojave, I had enough. I guess it had to happen once, after all these years (since 1998) without much hassle, if any at all.
I'm afraid we are but a tiny minority but I hope people at Apple are aware of it anyhow.
And no, I didn't check Activity Monitor, but I think notcloudy are onto something up here above. Perhaps the system is conversing everything to the new file format? But if that is the case, it would have been nice with some kind of info about it, methinks.
I am missing the little info we used to get earlier when installing and upgrading. At least something to look at 🙂

Perhaps you are on to something here. Yes, Apple introduced a new file format recently - AFPS instead of HFS+ or MacOS Extended. I had expected some conversion when I upgraded to High Sierra but it didn't happen and the harddrive on my new iMac is still MacOS Extended. I was a bit confused because of this, but there was no clear information as to what one would need to do, if anything. But if that is the case, the least one would expect is some useful info about it. Perhaps before the installation starts. Something.

On my MBP mid2014 ( specifications in the signature) I have serious problems with Imovie .... sluggish absurd, crashes, what ever happened with previous versions .... I also have problems with the flickering of the dedicated video card (nvidia gt 750 M) .... unfortunately I think it was born bad this Mojave, hoping not to end Ios 11

For me it seem to slow down extremely badly for no apparent reasons today.

It was extremely slow the first few days after update. Then it seem to run fine for a few days. But its extremely slow again today.

There's nothing eating resources in Activity Monitor. Just a bunch of apps that are not responding. But if you wait long enough, probably 1 - 5mins, they'll start running one by one.

Ver weird and inconsistent behavior. I plan to backup everything and do a clean install. This is a late 2012 iMac I'm running anyway. About time to do a clean install.
