Catalina and the end of 32-bit apps

You have probably heard that Mac OS Catalina, 10.15, will end support for 32-bit apps. Sounds geeky, and it is in some ways, but here’s the bottom line: some of your applications will quit working. Period. End of story. 

Here’s what Apple says:

So… what to do?

1) find out which apps you have that will quit working in the next 60 days if you upgrade to Catalina, when it comes out.
Here’s the easiest way: this free app:

(there are more less convenient ways to find your 32-bit apps, using Apple software) “

then you can
2) simply not upgrade to Catalina (or put them all on another computer that will never be ugraded.)
3) wait for the app developers to republish their software compiled for 64-bit
4) toss them out and find a suitable replacement
5) run El Capitan (10.11) in a virtual machine. (That’s my choice.)

Virtual machines

If you have Parallels or VMWare (probably to run Windows) you can find a copy of 10.11* and install it, to run it virtually. Then all you need to do is move your 32-bit apps to it, and away you go: you can upgrade to Catalina, but keep El Capitan around inside your VM.

*You can actually choose any OS prior to Catalina to virtualize. I went with El Capitan since there are trusted opinions that it’s the most suitable. Obviously, if you have some 32-bit app that requires, say, Sierra, then that OS would be your choice.

It has been my personal experience that Parallels works surprisingly well in general.

Do you REALLY have CAT 6 cable?

The new cable is here! The new cable is here!   (an homage to Steve Martin…)

BlueJeansCable is the real deal for ethernet and hdmi (and other) cables. It’s also expensive.

I have a DOCIS 3.1 modem, and an Linksys EA9500 router/wifi. I’ve got 1 Gb service, and I probably have 30 (or more) things hard wired up to the network.

I have just installed some BlueJeanCable CAT 6a certified ethernet cable. It runs from my modem, 23 feet to my router, and 23  feet back to my 24-port gigabit switch. It is significantly fatter, and not as flexible as CAT 5 or 6.   (I had been using certified CAT 6  – no “a” on the end).

Do you remember when the internet was described by some politician as “a series of tubes”?

Well, and this is just anecodatal, but the difference between the cables (CAT 6 vs 6a)  makes it feel like someone “greased the tubes.” Access now just flows.

No, I didn’t test it… this is purely subjective. Things are just “snappier” now.

I’d hope so since the two 23′ cables cost almost $90 with shipping. Like I said “expensive.”

Here’s a bit of startling info:  http://www.bluejeanscable.com/articles/is-your-cat6-a-dog.htm

(FWIW, I also use their HDMI cables. Also a noticeable improvement.)

Finally, I do NOT use BJC cables everywhere… they are just too expensive, so I  only use them at critical junctures.

I hope this helps (or at least intrigues) someone.
