Great app and all but... - as all the other reviews have stated: it hogs your computer tremendously. I even followed the directions to permanently delete all of the application's files but somehow it was still running logs into Console. I kept searching everywhere to find where in the world are those logs coming from even after I had permanently deleted it's files. Eventually, I ended up in Activity Monitor and searched for everything directly related to the solar app and quit the processes. So far it has not given any logs into Console and everything is going much smoother. Delete the files and the processes on Activity Monitor to permanently stop it writing logs and make your computer run faster. Other than that, the keyboard itself is really great.

Resource Hog! - The application is very, very poorly implemented, and a mess. Whether or not the application is running, and whether or not the Solar keyboard is connected, and even after you remove the application itself, it runs a "Solar" from your Library/Application Support/Logitech folder. It constantly writes to the system.log, several times a second, resulting in 4001 entries in the log file and creates a truly huge file, running to hundreds of megabytes or more. Worse, you can't see anything else in the system.log file because this writes so much and so fast that it destroys other entries in the log file. It uses single- or double-digit percentages of your system resources, too. If you have it installed, check your system.log using the Console utility, and you'll see what I mean. Or use the Activity Monitor or another similar utility to see the resource drain. I first noticed the issue via iStatNano, a Dashboard widget. To remove the full set of files, you have to shut down the service, remove the application and all the support files, and then force empty the Trash. The keyboard is great, but this application is not necessary to use the keyboard.

Review by Alienraygun

Spams Console, Updates Neglected - As stated in the numerous reviews before this one, this app spams the console with around fifteen messages per second. On the surface the app is great, it tells you in real time if the solar cells are picking up enough light to keep the batery charged with a software light meter and what percentage of your battery is holding a charge. It's pretty and it functions well but the console spam bug kills the usefulness of this app. This is bad software engineering and while Logitech makes great input devices (I love my K750!) they should be ashamed to have this app in the Appstore for so long without any updates or fixes. In my opinion, no one could complain about Logitech's K750, 760 series of keyboards on the Mac platform if Logitech would just fix this app. Note: The version number on their website is 1.0.1, I believe it is the same version as the one here on the Appstore. This version may be mislabeled.

Review by Hightray

Spams console log but found a way around it -- Otherwise useful. - Yes, it does spam the console log and I too did not like that. But there is a way around it. You can tell syslogd to ignore those messages. I have not seen any CPU hogging and the messages have stopped after doing this: 1) Open up a terminal session. 2) Edit the /private/etc/asl.conf file with vi. Ex: sudo vi /private/etc/asl.conf 3) Add the following lines: # Ignore message from Logitech Solar App ? [CS= Sender Solar] ignore 4) Save the file and reboot your machine or restart syslogd. 5) To restart syslogd: sudo launchctl unload /System/Library/LaunchDaemons/ sudo launchctl load /System/Library/LaunchDaemons/ Granted, it really stinks that you have to do this but I find the application useful as I want to make sure that my K750 solar keyboard is getting enough light. I do not want to be in a pinch if the thing dies on me. From what I have seen, there has been no response from Logitech on this issue. I hope this works for you. I really do like the app otherwise and find it valuable. If they fix this issue, I would definately up it to 5 stars.

Review by palsgraff

Useful app with one flaw - I would give 5 stars for the simplicity of this app and the well-thought out user design (plus it's got great polish), BUT… I can't figure out why everytime I launch it (either by launching it directly from my Apps folder OR by pressing the 'check light' button on my K750 keyboard), two duplicate windows open up (one of them being the "active" one and the other just a dud). I've tried uninstalling and reinstalling, hasnt' changed a thing. Everytime Solar App is launched, two app windows open simultaneously. Can't figure out why… If the dev team is listening: please let me know why!

Does not work with K760 - Not sure why Logitec decided not to update the Solar app to work on the K760. It would be nice to have this supported.

Review by Chief Points

This app causes massive system log files in OS X ML - I'm not sure how it's going on previous versions, but if you run this application on Mountain Lion it continually writes to system logs, creating extremely large and useless log files. This is a very serious bug. If you have Mountain Lion, do not install this application. I'm skeptical that logitech will work to fix it though, as it took me nearly 2 years, along with BBB complaints and State Attorney contacts, to get them to fix their Logitech Harmony remote software for OS X. Thankfully it isn't necessary to use the keyboard, but it sure would be nice to be able to use the application to monitor battery.
