You need to consider whether you really want to change anything.
I have not done a full RTFM.
Once you do, if you still want to proceed, you should find that most of, if not all of, your queries are answered in
POST 1
. However, not everything is covered in absolute detail.
In any case, I get enough moans about
POST 1
being complicated because I have tried to put as much background info a user may need to fly without having to check back ... as long as they do a "RTFM".
In summary though, MyBootMgr will create OpenCore instances that can boot "Vanilla" installations of Mac OS Tiger to Monterey. Instances installed via DosDude/OCLP without "Post-Install" patches applied are effectively "Vanilla".
There is a process for incorporating OCLP patched Ventura/Newer described in
POST 1
. DosDude/OCLP Patched Monterey/Older instances can be handled but this is discouraged for most users. I do run DosDude Catalina myself though and having this is a good idea on MP31 in particular or if using a recent (2020ish) GPU in general.
I am using OCLP 1.3 and am pretty happy with it except for the fact of having to option-boot for Mojave, Windows 11, and (optionally, not required) DosDude patched Catalina. I currently have Monterey, Ventura, and Sonoma all running parallel configs that are identical. My CMPro has a flashed RX-580 and updated WiFi/BLE. AirDrop and Watch unlock work. Mojave and Catalina have plist patches and run with full SIP. Monterey OCLP runs without root patch.
In your case, with the RefindPlus|OpenCore set up by MyBootMgr after you select certain expected options in MyBootMgr's ConfigFactory app, RefindPlus will always load on boot and you will be able to go to Windows, Mac OS or OpenCore. Linux will be detected and presented if installed later.
Will suggest running MyBootMgr from your DosDude Catalina so that DosDude Catalina is the Mac OS option displayed in RefindPlus by default. Possible to add the Mojave instance but will leave that as homework as best to stick to one Mac OS instance via RefindPlus and use OpenCore for the others.
I expect you will have four OpenCore instances:
- For BigSur/Monterey - Runs
- For Catalina/Older - Runs (Do not use for DosDude Catalina; should always be run from RefindPlus)
- For Monterey/Older - Installs/Updates (VMM)
- For Ventura/Newer - Runs/Installs/Updates (OCLP)
The first three work OOB but you will need to overwrite the fourth one with your OCLP instance as documented in
POST 1
.
The modifications you have applied for older OpenCore will most likely be automatically added by the ConfigFactory app as it probes your hardware and sets OpenCore up accordingly as much as possible. If there is something missing, you can script MyBootMgr's WrangleConfig tool to apply your arbitrary changes every time you run the ConfigFactory app. You can also set this up to automate the OCLP sync.
Note that each OpenCore instance created will show all available Mac OS instances as options but you must only boot what each OpenCore instance is set up to boot. It is possible to hide stuff that cannot be booted on the OpenCore instances such that only what is bootable is shown. Had wanted to automate setting this up but faced certain headwinds that frustrated this and have put this on ice for now. You will have to do this manually if you want to hide such. Refer to the OpenCore manual.
Does RefindPlus support the custom themes for the original?
If you mean
rEFInd
by "original", then yes, this is documented in
POST 1
.
On the OpenCore side, note that OpenCanopy is not configured by ConfigFactory and there are no plans to change this. Whatever is set in OCLP configured instances will work but MyBootMgr configured instances do not include this and you will need to add such yourself if you want it. This addition, as with any desired arbitrary changes to ConfigFactory output, can also be automated with MyBootMgr's WrangleConfig tool as required. You just need to add the code and run the tool.
IMPORTANT
Do not indicate that you intend to boot your DosDude Catalina via OpenCore when running the ConfigFactory app. That is, as it should always be run via RefindPlus, you essentially do not have a DosDude patched Mac OS instance for consideration when setting OpenCore up.
All said and done, you absolutely need to "RTFM" in POST 1
if you do decide to proceed!!
