Wondering what the differences are between the two apps.
If you use one of the two or both can you chime in how you like it?


I'm looking for something which will keep a graph log (trends).
Did you just do some DIY repair on your Mac, that would cause you to suspect faulty sensors? If not, the best approach is to ignore your temps and just use your Mac. Sensors are rarely faulty and your Mac will manage temps and fan speeds without any need for 3rd party apps.

No. At work we have a Mini that sits in a cage but I think it's pulling in hot air.

We have had several hard drives fail on us.

I have moved it to another spot, would like to monitor temps and fans.

Email alert would be a big plus.

Hard drive failure is relatively common and doesn't necessarily suggest it's temp related.

Just installed the latest version of TG Pro and found that it now tells me my battery (at 1277 cycles in 5yrs and still at 88% capacity), is 277 cycles beyond its "design limit". Haven't ever found Apple reference such a "design limit", not sure where they got that from but have asked them.

Other than that the update seems fine in use.

I just replied to your email although for public knowledge, here it is:

There does seem to be a design limit that is accessible through the right code. TG Pro calls IOPSGetPowerSourceDescription(), and for the internal battery, if the "DesignCycleCount" key is available, it will use that in the battery health message. On my 2015 rMBP, the design cycle count is 1000.

This isn't officially documented by Apple, so I can't point you to a page to see this. I hope this helps to answer your question and provide some validation that this isn't some random, made up number.​

Well calling it a "Limit" in your software seems misleading and scaremongering to zero benefit. What Apple DO specify in their battery info is that batteries falling below 80% at 1000 cycles will be replaced - if 1000 cycles was end of design life that wouldn't be a sensible statement to make in conjunction with a policy of the battery being a consumable item I feel. My 2011 MBP also has a design cycle count of 1000 according to your software so it would seem a wide range of models/years will be using the 1000 cycle count.

So you seem to have extrapolated from it being a "design cycle count" as called by Apple to becoming a "limit" in the error message. Nowhere can I find Apple stating batteries have limits such as that, that interpretation is simply misleading IMHO.

I honestly didn't mean to offend you by the choice of words in the app. I would not benefit at all if people replace their batteries, so there was no intention of scaremongering.

What I do agree with is that the wording could be better and I'll modify it in the next update.

I use iStat at least. Quality parts huh ?

I had an issue with a heat sink clip and bought some (to backup data) by running full speed. Then after a fix confirmed all was good.

Have been very happy with TGPro.
