macOS 10.15 Catalina on Unsupported Macs

[borgo1971]

In the configuration the patchers are currently using, it's not possible to enable SIP and managing to do so would only cause problems.

OK, I suspected that enabling SIP could broke something. Thanks for your confirm.
And I said that MacBook now works flawless, but that's not quite true.
I discovered today that a problem I had with Mojave also occurs with Catalina. It's something that doesn't happen always, but often when I go to Google Maps with Safari, the page crashes all the time (Safari remains still open and working).
I wonder if it's caused by the GPU being disabled, or how I did it, patching nvram and removing all the AMDRadeonX3000 * and AMDRadeonX5000 * extensions. I did so because when I tried to use Dosdude's dGPU Disabler, get even more problems with my MacBook Pro.

Reminder: For SIP to be completely disabled, the command csrutil disable restart your computer, MUST BE run from the Terminal in Recovery Mode or from the Terminal when booted into the USB patcher used to install macOS.

I disabled it more times. Or better: I gave the "csrutil disable" command several times. First of all, booting with USB patcher. I'm wondering if resetting PRAM will enable SIP.
In any can now it's disabled, I learned to verify it with "csrutil status" command.
Another question: can SIP be disabled booting in single user mode too (not form recovery or installer)? Recovery won't boot my MacBook Pro with filed GPU...

A single PRAM reset in my experience doesn't but if you it 3x in succession, it will clear all PRAM parameters and SIP is re-enabled.

SIP must be disabled in Recovery mode but not other modes, and just once for all different booting partitions.
I seem to recall that one of the Boot Loaders or OC is now able to directly disable SIP via NVRAM editing.

Um this is kind of relevant to unsupport Mac thread, does this card work nativity on Catalina. If not does it at least have open gl support work/acceleration. I prefer to have this card work with metal. Its a zotc gt 710 ddr 3 card. Here’s the exact version I have. I plan to use open core as well or clover possibly.

 

[tom33231]

And yes I’m back for a bit, but really only for a day. I have been very busy with school. I am only a Sophomore in college.

No Recovery Mode. USB patcher the only option. NVRAM reset does not re-enable SIP. SilentKnight accurately reports SIP status, FWIW

Just triple-bonged this Mini3,1 w/NVRAM reset and SIP is still disabled. Reset NVRAM w/OpenCoreAPFSloader3, same result.

That is a bit puzzling
The SIP status is stored in NVRAM.
Doing a PRAM reset would clear NVRAM.

Reset NVRAM on your Mac – Apple Support (UK)

If one or more settings stored in NVRAM aren't working as expected on an Intel-based Mac, resetting NVRAM may help.

support.apple.com

Maybe that is an incomplete selective clearance of PRAM only without affecting NVRAM? In the past Apple recommended 3 consecutive PRAM to clear all NVRAM.
In my iMac 2010, whenever I did the triple PRAM in Catalina or High Sierra (both without OC), SIP is re-enabled.
Thus, I avoided doing so in consecutive manner.
I check the status in Terminal.
I am not sure whether the latest OC can directly change the NVRAM value or not.
According to OC documents, OC can disable SIP thru Config.plist by setting the csr-active-config value in the EFI partition of the system disk.
Then despite PRAM reset, it could have been disabled by OC.
I don't have throughout knowledge of OC, and am just conjecturing from my own observation.

High Sierra on the 2010 iMac is supported and SIP can be safely enabled. Catalina is unsupported and enabling SIP results in the Prohibited icon on restart.

That I know
The issue here is whether a PRAM reset will clear NVRAM and re-enable SIP without OC.
My experience is NOT with a single PRAM reset but YES when done in consecutive succession in my iMac.
A single PRAM reset will change to the default boot partition (and probably some other parameters) but not affecting SIP status.
It is possible that the scope of PRAM reset may change with the newer Macs. I am not certain.

Not having a Catalina-supported Mac handy, can't confirm. However, since a @dosdude1 patched Mac disables SIP as a matter of course, the point is moot. No matter how many bongs are applied. ?

It´s a choice. isn´t it?

Hi, i have iMac9,1 Catalina 19H15 with 2.1 + EDR and my Airpods connect after fresh reboot no problem, even sleep - wake still connects, but sometimes when iphones autoconnects then imac can't take over and from that time they cannot be connected until reboot again.
Trying that with BT dongle 4.0 but it behaves more less same, with error that dongle dont show up after sleep-wake
Any recommended way to make Airports work (remove internal BT and use only BT4.0?)

Hi there, all of a sudden Zoom won't let me login anymore on my MBP8,1 with Catalina Patcher. I've tried to reinstall Zoom including what I found in Library (still no login), two other supported Macs (login works), and someone else's Zoom account on my patched MPB (doesn't work). So it could have to do with the Patch. Does anyone know this issue - or even a solution?

Hi there,
After installing the H505 update, my magic mouse is annoyingly disconnecting and reconnecting in a random manner.
I've experience this yesterday and today as in 5 times in an hour... or as little as 1 time in an hour.
Anyone experiencing the same?

http://dosdude1.com/catalina/zoomnonmetal.command.zip and http://dosdude1.com/catalina/zoomnonmetal-new.command.zip - have you tried these patches from @dosdude1?

With the exact same iMac on H505 for a week, no problems at all.

Using a wired keyboard and mouse - From the Bluetooth(BT) Control Pane: Un-pair (disconnect each connected BT device), turn off Bluetooth. Insert dongle, now.

Switch to the host controller in the dongle. From the Termnal, type: sudo nvram bluetoothHostControllerSwitchBehavior=always Enter password and restart. (To remove this change, in the Terminal, type: sudo nvram -d bluetoothHostControllerSwitchBehavior Enter password and restart returns to the built-in BT host controller.)

From the Bluetooth(BT) Control Pane: Turn on BT (if it's not already on) Pair each BT device. No more conflict or interference. enjoy

Actually if you press Shift-Option/alt key together and click the top menubar BlueTooth icon, you can bring up the Debug menu to reset the BlueTooth module or remove all BlueTooth devices.

If you install your new BT 4.0 module, remember to remove the old 2.1 module or it will cause interference trouble. Some use the BlueTooth Explorer app to disable the old module in software mode.

Yes. And Zoom's camera test in Preferences works. But I can't log in.

EDIT: Now I tried an SMC and PRAM/NVRAM reset - one (which?) of these solved it.

Are you disputing the method written? BlueTooth Explorer app only works until the next restart.

Hey guys! I decided to update my MacBookAir4,2 from 10.15.5 to 10.15.7 and got a Wi-Fi issue. Updating to 19H505 did not solve the problem either.

So the issue is that now it simply does not see any networks and does not want to automatically connect to my router too. Instead currently using:

networksetup -setairportnetwork en0 ssid password

for manual connectivity after each reboot or going out of sleep.

I have seen some of the traces of this issue for other people previously here in this topic, but any actions like resetting settings does not seem to work.

Any help would be greatly appreciated!

In the Utilities ƒ find the Patch Updater, control click on the appropriate WI-FI patch, re-install the patch and restart.

Just options. No dispute
Have a good day.
