I've just bought a new Macbook Pro and when I run Cafetran on it, the computer heats up to the point that it is uncomfortably hot to the touch near the location of the vents at the top edge of the computer body. I don't have a utility to measure temperature, but Activity Monitor tells me that Cafetran is using 40% to 69% of CPU even sitting in the background with nothing actively going on in the program. Constantly, for as long as I have it running.
I have been very happy with Cafetran and would hate to lose the utility of the program, but I'm not ready to fry my new Macbook, nor to ruin the battery from the heat. Is this normal behavior for Cafetran on a Macbook? I see that someone in another thread had a similar problem--albeit not as severe as mine--on a Macbook with similar specs but a 2014 model. Mine is a 2015 model, running OS Sierra. I would be very grateful for any ideas on how to get around this problem. I would really like to keep working with Cafetran, it's a fantastic program.

Okay, it's been added to the latest build.
Just noticed that in the lastest build cmd-v and cmd-c are now working as expected with the metal look on my Mac. Thanks Igor.

Using metal look also brought down cpu usage and battery drain (a lot) on my macbook pro. However, and in case some were wondering, be aware that some short-cuts have changed. For example cmd-c and -v are now ctrl-c and -v.
Sorry to hear that you're "gone", Patrick. If you at any point decide to give CafeTran another try (to enjoy its fabulous handling of Studio packages), please feel free to contact me again and request my help. Always glad to help you.
Great, thanks! I have just added the Metal Look & Feel point to the article on running CT on battery power:
THAT'S IT!!! After switching to the metal appearance option, CT's CPU usage is ranging between 1.x at idle and around 8 when I'm using it. What a difference. Since the metal option doesn't integrate Cafetran into the Apple top menu, the problem must have something to do with that. Thanks a bunch—I was really afraid I was going to lose the use of CT. You saved me, Igor.
Okay, thanks, I'll give metal a try.
There is no single line of code change in CafeTran functions on various operating systems. CafeTran only uses Mac Look & Feel by default on Apple operating systems. I did notice that Metal Look & Feel (see the Preferences > Appearance tab) seems to have lower CPU usage on my Mac. You might try that.
No, indeed I have the latest version of Java on the computer already. It also occurred to me that the fact I had an image background might drive the energy consumption up, so I went to the default background, but that, too, did nothing to fix the problem.
Okay, thanks, I'll try updating, but I may have the latest version already -- I just installed Java on the computer this week.
