Mac Models Thus

The Broadcom card mentioned in the kit is used in many iMac models thus natively supported by macOS.

Some smart guy sells similar kit for around 215 USD shipping but normally you get it for less than a quarter of the price (and free shipping from China).

Theres a version of the mPCIe adapter that doesnt require soldering Amazon, Ebay.

D and D- connectors on the mPCIe adapter must be connected to the motherboard instead of the old Bluetooth card.

Wi-Fi card is highlighted on the left and the small Bluetooth card on the right.

Later we will be passing wires behind the area highlighted in the center.

Connect three existing Wi-Fi antennas and one Bluetooth antenna extension cable to the card exactly as shown below.

Tighten the adapter in place with one of two screws holding the old card.

In particular the issues with Mail and Preview, both of which I totally depend upon.

Thoughtful, detailed coverage of everything Apple for 30 years and the TidBITS Content Network for Apple professionals.

Two of the vulnerabilitiesthe same ones addressed in last weeks updates to Apples other operating systemsmay have been actively exploited in the wild.

However, no mention was made of a recent vulnerability discovered in the sudo Unix utility.

Mac OS Going Back

The external monitor works as it does with earlier Mac OS going back to Snow Leopard, although the display control panels have changed a little over the years.

If youre running an Apple monitor, even an older Cinema Display, this article may help: How to connect your old Apple display to your new Mac Macworld.

Apps refuse to launch because I dont have permission to launch them, and this happens only after a long pause while the OS struggles to figure out what to do.

The OS seems to prefer to launch them when I double-click on the app rather than click on the icon in the Dock but I dont think thats always the case.

I often come back to my computer and get a message that some program crashed, most often Safari but it was NetBarrier a minute ago.

Oh, and SuperDuper still hasnt been updated by its developer, who blames Apple for a half-baked roll-out.

By the way, none of my Big Sur problems went away after I installed v.11.2.

Apple is so busy fixing security problems that it apparently hasnt had time to address the actual usability of the OS.

Id recommend reinstalling Big Sur and seeing if that resolves any of the issues.

Another possibility is that your Mac has started suffering from a hardware problem at roughly the same time as you upgraded from Catalinaif its related to failing storage, it could even have been triggered by the upgrade.

That said, my iMac Pro has not yet needed my ThunderBay SoftRAID.:: I will be testing that eventually.

Free, various sizes, macOS 10.15.7 and 10.14.6).

I checked my boot drive twice with Disk Utility and it passed with flying colors.

As CNET says in a 2013 article at What to do when a Mac wont boot to Safe Mode - CNET, Id first have to disable FileVault and remove my firmware password.

Ridiculous. I cant boot into safe mode by holding down the shift key on my iMac or my MacBook Pro because of this.

Ive tried it many times.) Anyway, the app launching problems have become intermittent.

I thought they had perhaps gone away but no, I just got another error message of the same type.

I will never give Apple the benefit of the doubt, not after my experience over many years.

If the only thing holding you back is the firmware password, Id just disable it for this test.

I have a copy loaded on a separate boot partition and I keep it up to date but my production machine with all my licensed software remains on Catalina.
