@Syncretic I was told by @cdf to report that I don't have any race conditions with your failsafe (default) settings and OC 0.7.2. I see some users use higher values and debug mode, I just want to let you and everyone else know that I have zero issues. I currently have one Mojave SSD in Slot 1 and two Samsung EVO Plus mounted into Syba SI-PEX40129, one Big Sur 11.5.2 and one Windows 10. You can look at my custom OC setup.py settings file (the rest defaults to failsafe values), in case you want to compare.

I upgraded to 11.5.2 with default settings, without any issues.

I don't know if this is directly caused by Latebloom, but I have been seeing more items like the one in the attached image since I set the latebloom value to 96. I have not clicked on these items because I am afraid of corrupting the system. What's this?

IMG_1352.JPG

Next, please tell me about the optimization of the latebloom values.
I'm testing it by increasing or decreasing each of these three axes: 100, 150, and 200. In my case, I'm feeling good around 100, so I'm decreasing one by one and "96-97" seems to be good. Comparing 100 and 96, I may not see much difference in the impact of it. A placebo?
But there is one thing they all have in common, and that is "reboot(warm boot)". I have verified this by varying the value of latebloom, but I have never had a successful reboot. The progress bar stops progressing at about 1%, or the start-prohibit icon is displayed. What is the success rate of your reboots?
Is this caused by FusionDrive? I am curious about one thing. I have noticed that when I look at the disk number of the media that makes up my FusionDrive in the terminal, it fluctuates. The SSD is fixed at disk0. However, the HDD fluctuates between disk1 and disk2 every time I boot my Mac. When disk2 is assigned to the FD HDD, disk1 will be assigned to a completely different, fixed HDD. This HDD is installed in the optical drive bay. What is this phenomenon? *I have OC installed on FD HDD.

I just noticed that Hyper-Threading is disabled. I know, it's not latebloom. But is this a requirement for the config?
Just checked. Booting into Catalina with and without OC I have Hyper-Threading. Running Big Sur 11.5.2. with latebloom it is definitely off. Same config except for the conditional latebloom loading.
Of course, no cwae=2 boot-arg.

I had a very bumpy update to BS 11.5.2. After nine boots (three of them for the install proper), I finally reached the desktop, only to discover that the latebloom 0.20 hook hadn't been set! After that single ninth successful boot, I reverted to latebloom 0.19 and have had two successful warm boots (and no hangs) ever since. Here's the report:

They are TOOLS that have been explicitly enabled in the OC config.plist file that you are using from wherever you sourced that file.
If you do not know what they are, you probably do not need them and you can remove them from the config.file.
Their functions are documented in the OC manual.
They are nothing to do with latebloom.

E.g. you can either delete the item or disable it in config.plist

Screenshot 2021-08-12 at 13.22.03.png
Setting HideAuxiliary to true will HIDE them in the OC Bootpicker but not remove them. To view the hidden items in the bootpicker, press the Space key. Setting HideAuxiliary to true will ONLY hide the item IF Auxiliary is set to TRUE in the above example.

I think it needs to be mentioned that the race condition during the update process can be very different than during normal operation. In my case, the 11.5.2 update required several hard restarts. Fortunately, my previous boot stability seems to have been restored after the first boot into 11.5.2 ?

Note: I used the default parameters (60/0/0).

^I concur, although, in my case, I might have inadvertently installed BS 11.5.2 without latebloom and the first successful boot to the 11.5.2 desktop might have also been without latebloom. All two later warm boots using latebloom have been successful.

I had good success installing 11.5.2 - three no issue reboots during install and a hang on the final boot to the desktop. Subsequent boots have been fine. All using 100/0/1.

My experience as well - I totally failed to update via the "Software Update" system pref panel. Eventually aborted after 14 hard shutdowns. I was able to boot into Mojave, check the OC install was all okay and then shutdown and startup off a backup disk (11.5) and use that to install from a 'full' installer I downloaded. Worked first time!

Hi all, here's my feedback after update from 11.2.3 to directly 11.5.2 via OTA.
I've started with LB:100 R:20 but without 2 "spare" sata drives. Then after update I attached them back and I had one failed boot. I then tried LB:150 (like code attached) and for now (after 2-3 warm/cold boots) and it seems stable!
Thank you all for your awesome work!

Just checked. Booting into Catalina with and without OC I have Hyper-Threading. Running Big Sur 11.5.2. with latebloom it is definitely off. Same config except for the conditional latebloom loading.
Of course, no cwae=2 boot-arg.
Am I the ONLY one without Hyper-Threading?

SOLVED! Big Sur seems to have revamped thread management and core allocation. The big cMP loafs most of the time. I decided to throw a beefy Xcode compile on it - and voila! Hyper-Threading does show up!
Catalina and earlier always show full use of 24 cores while Big Sure appears to use real cores only until Hyper-Threading is needed due to high loads.

The 11.5.1 update to 11.5.2 took 7 hard restarts until it completely installed.
Bluetooth was not detected on the first successful loading but was detected on the next warm restart.
All cold and warm starts since then have been without an issue so far.
No change in my latebloom parameters 100,20,1

I think it needs to be mentioned that the race condition during the update process can be very different than during normal operation. In my case, the 11.5.2 update required several hard restarts. Fortunately, my previous boot stability seems to have been restored after the first boot into 11.5.2 ?

Note: I used the default parameters (60/0/0).
I wonder if using sudo softwareupdate -i -a in terminal to update macOS will make any difference.

just to say that I had the same exact bluetooth behaviour when I updated from 11.2.3 to 11.5.2. At first I was worry about I lost bluetooth...

Finally got to 11.5.2 using 150,20,1; tried 100,20,1 and it went back to the old hang time. Have retreated back to Catatonia as BS went to sleep whilst I was away for a while and refused to wake up. Had to use the power button to bring it back, so will wait to see if progress with Latebloom and OCLP sort this out.

A tip for getting to 11.5.2 make sure that you are monitoring the booting progress with -v in the NVRAM boot-args string. That way you can see where the hangup is in the booting progress. I found there were several hangups at one particular part of the process and kept re-starting looking for the process to advance. Eventually it did after 7 power off shut downs and restarts. If you see a stall, do not give up.

It would seem I have lost bluetooth. Been through at least four cold boots since updating but sadly seems its gone and not coming back :( wifi okay

Sorry, but that's off-topic. Simply upgrade your BT/Wi-Fi module to a supported model.
