Keyboard, keypad glitch after Security Update 2015-002

The overview is: keyboard problems developed shortly after Security Update-002 on Mavericks 10.9.5. I tried OS update to Yosemite; didn’t fix the problem. Reverted OS back to 10.9.5 using Time Machine for a backup date prior to the Sec Update; this fixed the problem.

Mac mini5,2, 16gbram, wired Apple Pro Keyboard (M7803, circa Mac Cube), Apple Wireless Keyboard, LMP Wireless Numeric Keypad, Apple Magic Mouse (A1296?) iPad 2

Within the past 2 days, Apple BT keyboard alpha keys stopped typing. During troubleshooting, I discovered that problems extended to BT keyboard, BT keypad, and wired spare USB extended keyboard. The BT keyboard pairs and works fine with my iPad. Here’s a list of the glitches:

Apple Wireless keyboard:

alpha keys NO INPUT

space key NO INPUT

Delete key works

Force-Quit sequence works

fn, cntrl, opt, Apple, arrow keys, shift all work

top row keys work

LMP Bluetooth keypad:

keypad: 1..4, 6..9 NO INPUT

keypad "5" registers a mouse click, NO INPUT

keypad "0" jumps to mouse cursor first press only, NO INPUT

=/*-+ and arrows work

Apple Pro USB extended keyboard:

num keys: 1..4, 6..9 NO INPUT

keypad "5" registers a mouse click, NO INPUT

keypad "0" jumps to mouse cursor first press only, NO INPUT

alpha keys and number row keys work

keypad =/*-+ and arrows work

Besides proving the wireless keyboard works on my iPad, I reset PRAM with no improvement. (I had no problems with my Bluetooth Magic Mouse.)

Next step was OS upgrade via Software Update to Yosemite. All above glitches remained.

Next, I reverted to Mavericks 10.9.5 using a Time Machine OS backup dated prior to 9Mar15, the date of Security Update 2015-002. After this, both keyboards and keypad resumed working. Seems clear that the Security Update is the culprit, no?

I reported the issue to Apple via Support Chat.

I would like to eventually upgrade back to the Security Update and Yosemite but not when it breaks my keyboard. Perhaps I could skip over the Sec. Update and go to Yosemite? Any suggestions?

Mac mini, OS X Mavericks (10.9.5)

You can do that. Make a backup before upgrading.

Update:

The day after I reverted to 10.9 to repair keyboard glitches caused by Security Update 2015-002 (and persistent in Yosemite), Apple released Security Update 2015-004. Such a quick succession of -004 on top of both -002 and -003 was the hint to me that -004 contained fixes to the glitches.

I crossed my fingers and jumped back on the install-wagon. Yosemite 10.3 completed its second installation and my keyboards/keypads remain functional!
