Yes, it's a known issue with High Sierra on the 2012 - 2013 MacBook Pros with Nvidia graphics. Frustrating that Apple has done such a poor job optimizing the OS for slightly older (but still supported) hardware.

Mojave is better, but switching Spaces with multiple apps open still stutters.
Thanks. After spending a couple more days with the 2012 I just couldn't abide it any longer. Already sold it off for what I paid for it.
 
What are the boot up times like?

Having just upgraded my late 2013 rMBP to High Sierra, I'm disappointed that my boot up takes twice as long now. The ugly loading bar seems to take an age to clear.

MacBook Pro 2017, running really well for a DB1! It was a little hot at the beginning but it's basically back to normal now. One thing that I have noticed, however, is launch pad really laggy. So far very impressed with performance for the last 2 hours I've been using it.

EDIT: also, there is a slight lag when dragging around windows

Running on a 2017 MBP here too, and I have to say, it doesn't feel like a beta at all. Been putting it through its paces for three days now, and 0 problems have come up, including with programs notorious for not playing nice with Mac beta OSs (Photoshop, Premiere, Audacity, Wiretap Studio). No issues with any of my (many) Chrome extensions either. The only "extra" prep thing I did (besides a full disk image backup, duh) was to replace my stable version of Evernote with the latest beta, since I heard there were issues with Mojave.

I have to say, I'm almost ready to install Mojave on my main machine (but I won't until at least the first official release version)...and it's definitely staying on my #2 machine.
 
Runs much smoother than High Sierra on my Late 2013 rMBP w/Nvidia graphics. They've fixed a lot of the graphics issues which plagued High Sierra in re: Nvidia graphics. Stability was horrible at first, but reinstalling via Recovery Mode over my existing install helped - it's now very stable.
 
Just had my first issue with Mojave beta this morning: SuperDuper (disc image backup) does not work at all, crashes right after you tell it to make a backup.
 
These things rarely touch low level benchmark scores (unless it's a new API like metal), I imagine it's more real world like when a hard drive (very easily) reaches 100% IO, how does it handle that load so the user doesn't pull their hair out.

Be very curious for high quality in depth testing of Mojave on rust drives when the final build is out.


2017 macbook pro. Mojave beta 1 and Beta 2. SSD speed before was 2200 read 2050 write. After Mojave 1500 1440
 
I told myself after the experience with PB1 of High Sierra that I would never bother with testing a new macOS beta again.

Even after the Keynote, when they explained that Mojave was all about refining macOS, I still said I wasn't gonna do it.

FFW to yesterday, and all the screenshots I've seen of the dark mode finally made me crack, and I installed it.

I did a clean install from USB and IMHO, at least on my iMac, this is hardly a beta.

The only glitch I saw during the install was bringing up the Terminal from the installer screen, it was refreshing itself over and over when you tried to scroll. Other than that, the installation went without a hitch.

Performance wise, I would say the whole OS feels snappier than High Sierra. Only one app that I use has minor issues.

For my own experience, this is possibly the best PB that Apple has ever released.

That doesn’t sound plausible to me. I suppose it’s possible they have some debug code in during beta, but that’s a massive slowdown. Have you tried measuring again since?
 
Running Mojave PB1 on a 8 GB 2012 QuadCore 5,1, off of a platter based drive. Performance is unexpectedly smooth, except for some relatively minor graphics hiccups with some Apple apps it 'feels' fine. It converted a HFS+ hard drive to APFS by default, though.
 
GUI is much less smooth on my 2015 13" rMBP. But it was the same way with HS and even Sierra betas, they did bring the performance to a good level in the end.

In agreement but haven't noticed many issues with the GUI thus far. There's always time. :) Same MBP. I'm very pleased so far. No major issues (for a Beta) and and in love with dark mode. Finally!

Be brave. Unless it's your work Mac, do it man. Good stuff.
 
It doesn't appear like anyone wants to disclose this.
I am almost tempted to install it only to find that out. But it will be a PITA with the Hackintosh due to lack of drivers. Not yet.

(High Sierra takes less than 10 seconds to start on the Hac Pro. Everything except sleep works better on the Hack than it does on the actual Macs we have at home...)
 
I have to agree with some of the comments here....

I have tried to learn my lesson about running Public Betas.

That being said, this Mojave PB 1 is by far the smoothest running beta I have ever encountered.

I mean, I have been running it for nearly a full week now with hardly a problem.

It's buttery smooth.

Some problems I encountered...

1. Software like TotalFinder, Mailbutler (and other assorted mail-plug-ins) do not work. No big deal for now
2. News crashes
3. Cannot copy and paste images in Safari. Have already sent a Feedback report to Apple.

But that is about it. Most every program I am running -- and I am literally running more than a dozen at startup -- are performing perfectly with no hiccups. I mean, even PARALLELS DESKTOP works right out of the gate which has NEVER been the case with any previous beta.

The iOS 12 PB is also running very well on my iPhone.

I am simply amazed at how well a beta can actually run to the point that I can recommend it as a base operating system as long as the user backs up his/her data.

Boot time? I can't give exact numbers but it doesn't seem any different or slower than High Sierra. There certainly isn't any lag from Apple logo to boot up, though a slight lag for all the programs to start up once logged in.

That's not especially good.

I made a backup of High Sierra using SuperDuper prior to installing Mojave.

Now, if I have to go back to High Sierra I can't depend on SuperDuper to do that for me.

Thankfully there are no issues with Mojave beta.

That's interesting, thanks.

I went from Sierra where I could enter my password and I'd see the desktop almost immediately from cold start. At last count, after a reboot, High Sierra took 43 seconds to show me the desktop. I know it's hardly end of the world scenario, but it really puts a shade on the experience.

It seems random, but once you have it and can't disable/enable TRIM it's going to stay. While it's just 35 or so seconds longer in my case, that means it's 3x longer now, which sounds less nice.

I'm super tempted to install Mojave with sole purpose of checking that, but I would need to either run it from a USB-C stick or purchase a new enclosure... Not doing it on my primary machine, not doing it on the Hackintosh either.

Yet.

I know myself. *sigh* I'll be all over this forum three days from now if I'm lucky.
 
The problem is, in my opinion, is that you really can't properly gauge final boot time at this point. Since this is a beta, everything about this new operating system is going to improve as we move closer to the final release.

Doing my usual daily not-too-taxing stuff, I've found the performance of my late 2013 Macbook pro has stayed pretty much constant. If anything, I think it's sped up slightly since getting away from Mavericks and Yosemite.

Mojave might actually be a touch faster than HS too.

Absolutely, I'm just curious whether it's closer to 15 or 45 seconds from an SSD.
 
No speed tests, but since yesterday the beta 3 was released, the system is more fluid. Safari has more or less getting responsive. Don't forget, that we are on very early betas yet!

Still impressed? Truly noticeable change?
 
Did anyone experienced over Heating CPU temp on Mojave ?
On my Hack I have CPU high temp sometimes compared to High Sierra, even on idle state.

I'm investigating ...

Boot time (in my case) is almost 1 minute on rMBP 2015 with 16g memory / SSD - this is 2 times longer than HS and 3 times longer than Sierra - not trending in a good direction - but it is still early days in the Beta.

Also the OS seem to be busy for the first few minutes when starting - apps don't launch quickly etc.

Other than the slower boot time Mojave seems very similar to High Sierra

Edit - after about 7 or 8 beta updates - boot time is about 12 - 15 seconds - quite a change!
