TOPIC: Use of 6.0.6 (.8?) with OS 10.11.04 (El Capitan)

Use of 6.0.6 (.8?) with OS 10.11.04 (El Capitan) 27 Mar 2016 21:42 #7117

I have used the above version successfully with Yosemite, but thought I might be pressing my luck with El Capitan. Is it safe?

TT is installed on a separate HD on my computer and I restart with it to do maintenance, so I suppose it'd be easy enough to download the .8 update, but I've learned over time to not mess around when things are working.....or to first check out the advisability. Is .8 a significant improvement, and would I need it for El Capitan?

You should not use TechTool Pro 6 with El Capitan. You need TechTool Pro 8.0.3 or higher for compatibility with El Capitan. You can see the new features in the description in the online store.

Greetings from FineTuned Mac! :)

I think this question fits in here.

I realize that TechToolPro v 6.0.8 is not supported for use in OS X 10.11.4, but on a lark, I tried to run its Surface Scan and S.M.A.R.T. tests in 10.11.4 on a Mid 2010 15" MacBook Pro, and both tests ran successfully. (I did NOT attempt to run any aspect of TTP that interacts with OS X...ONLY aspects that interact exclusively with hardware.)

In the interim, I've gotten a new Mid 2015 15" MBP, and I've found that TTP does not play well with it at all.

It launches, but immediately spokes to 100% CPU, and when it eventually allows me to select a test to perform it balks (with an alert sound).

This is the record it leaves behind on Console:

5/16/16 6:52:02.081 AM TechTool Pro 6[26840]: Failed to set posix_spawn_file_actions for fd -1 at index 0 with errno 9

I realize that you may be disinclined from dealing with this question, but I'm wondering why the same version of TTP reacts differently in the same version of OS X, but on two different Macs?

Thanks.

I suspect that while the two computers have the same version of OS X, different system software files are coming into play to support the different hardware of the two models. You should not be using TechTool Pro 6.0.7 with either of these machines. Eve if a test appears to run properly, the result reported could be a false pass or false fail.
