Even if you re-enable Secure Boot after installing an updated driver, Catalina will ignore the update. At present, there exists no way in macOS Catalina to load a newer SoftRAID driver (or other driver) without disabling Secure Boot. Note that disabling Secure Boot entirely is the ONLY way to update kernel extensions in Catalina at this time, e.g., SoftRAID. ![]() ![]() But changing Secure Boot to just allow booting off external media should suffice. MPG: disabling secure boot entirely does NOT disable all system security verifications. On the downgrade instructions it says "You could also disable ‘Secure Boot’ entirely, but that is not recommended as it will, well, disable all system security verifications.” I had to do this to get it to work, but I reset the security settings after the downgrade and all is fine afterwards. Select your USB drive installer from the boot list. I’m sure other programs are causing issues for your readers. Our accounting software will not work using Catalina, so thus the reason to downgrade. I bought a new Mac mini 2018 that came shipped with Catalina I was able to roll back to Mojave using this method. Make a full backup first, preferably two.I’ve always found that to be highly offensive, but Apple keeps doing it. This has been true with every major OS release. Apple unceremoniously and without your consent irrevocably changes your data, so you cannot copy over or clone over a Mail folder or other data like mail, calendar, etc) the data formats will not be compatible.Calling it a downgrade is unfair to Mojave! Before “downgrading” back to Mojave. It is definitely an upgrade to revert to macOS Mojave from macOS Catalina. Unless of course you are Apple, and your problem is convincing users they need to buy new hardware all the while fully knowing the M1 processors are right around the corner.- SEND FEEDBACK Related: Apple, Apple macOS, Apple macOS Catalina, Apple macOS Mojave, security It is a solution to a problem which did not exist. No-one needed it, or wanted it particularly other software vendors who had to do all the additional work for compatibility, and for almost NO new product sales. ![]() Imho, Catalina is the OS equivalent of "New Coke". In many cases, such exploitable coding remains into further builds of the OS until reported, patched and then disclosed by the software vendor. A (within reason) older, more tested, and well patched OS is generally more secure because the more easily identified and remotely exploitable coding errors are found "quickly" upon release, and then patched. These new OS builds always contain more interesting things to find during initial auditing, and always make them much more targeted/given additional scrutiny. Newer OS do introduce new code, which has been tested by MS or Apple however, it has not been exposed to the scrutiny of the white/grey hat penetration testers/bughunters and outright hackers. Security is another issue, and a bit more complicated. No-one has yet suggested it runs anything any faster or more efficiently, and actually displayed convincing results of this. After that, you can hear the winds whispering. I have asked this often about Catalina, and I only get one reply which most agree is a nice new feature. ![]() instead, the newer versions often just add more bloat and of course, they do sometimes introduce very useful and great new things. but it's not usually the case where Apple or MS are re-writing massive sections of the OS coding. I know this can be achieved by the programmers writing more optimized and efficient code. it's not common for new operating systems to run much faster using the same hardware.
