Macbook pro waiting at %100 like 5 hours!

[MBPplotter]

Hi guys and gals!
I have macbook pro 16" 2019 with 16gb ram - 1tb nvme ssd (built in) - i9 (8 core-16 threads)
And i use chia software.

I have a problem about plotting. My computer waits too much at %31 and %100 (like 4 hours)
with this setup i can just run 3 plots in parallel and it takes around 12 hours.

I checked the files and they are still .tmp
I dont understand why my computer waits too much at %31 and %100.
Possible reasons:
1- Mac OS installed on my temporary space. So i need to get external nvme for temp space.
2- My 2tb wd elements desktop hdd connected to the Overhub | Elektron which dont have power adapter. So i need to buy a new usb hub with adapter.
3- My macbook pro also farming.
After your advices i will continue my investments.
Also here is the logs:

Plot size is: 32
Buffer size is: 3390MiB

And it still waiting at %100. Please help me

1. 269.305 (temp) + 101.334 (plot) = 370,639 * 3(thread) = 1 111,917 GiB - Not free space ???
2. 3 threads at the same time finished creating the plot, and copy the data to the ext hdd, which will take a long time.

370,639 GiB is used in the final stage,You need to make a delay between starting the threads.

The delay time is the total time to create a plot / 3.

To do everything accurately, you need to run the threads with your hands :(
We remember the start time of the first thread, and when it reaches 33% of the launches of the second and remember how much time has passed. When the second thread reaches 33%, the third one starts, and we record how much time it took. There will be a difference, since the two threads will load the SSD more heavily.

so second plot should start at %33 of plotting stage for first plot. but why %33 ? I read some discussions and ppl said after 1st phase of 1st plot, second plot should start. As i see first phase finished at %31 (if im not wrong). And my process stuck at %31 too much :( So should it start at %31 or %33 ?

[aa2001]

When 1 thread reaches 99%, the second will be at 66%, the third at 33%. Then the volume of temporary files will be about the same - 33+66+99 = 200% * 370,639 = 740 Mib. As soon as 1 thread reaches 100%, it will delete all temporary files, which will allow the rest of the thread to take this place.

ok i deleted the other plots and i am waiting for %33 to start second one after the experiment i will note the durations and make parallel plotting :) thank you

[MBPplotter]

I started second plot manually when first plot reached %33.
here is the results: I did not wait at %100 (thank you)
but we have some timing problem because when first one reached %99 the second one was at %21 :(

@MBPplotter , the newest version(s) of chia has fixes in place to resolve this issue. Please download it from here: https://www.chia.net/downloads/

Since this issue has been resolved with the latest version(s) of chia we will be closing this ticket but if we have closed this ticket in error do not hesitate to reach out to us again with any followup questions, comments, or if the issue persists after an update.

Please note that upgrading major versions of chia generally requires the config.yaml to be recreated using these steps:
1. Stop chia
2. Rename the config or move it to a different directory
3. In CLI run chia init
4. Copy any custom settings from the old config to the new (plot drive directories, pool info, trusted node info, etc) - be careful here as yaml is very picky about formatting including those leading spaces
5. Start Chia
