It's nice that Logitech FINALLY wrote this software for the Mac so I don't have to run it on a PC or VM of Windows anymore. However, the software is not without it's quirky issues.1. If you have the Alert software running for awhile it tends to hang up where the video displays for the cameras will disappear in the Alert window. The cameras still work and even the recording is still being taken and downloaded to the Mac but you have to force quit the Alert Commander software and relaunch it for the cameras to display inside the software again.2. Not so much a glitch but more of a "why in the world would they right it this way" kind of thing. When you launch the software it asks you to choose a camera site even if you only have one site to choose from. This is a waste of time and an inconvienence if you have the software auto launching upon login. Seems to me that if you only have one camera site then it should just launch to that site and if you actually have more than one site, then make you choose.Overall I like the Mac version enough to give it 3 stars but if they'd fix the two items above it would be a MUCH better app.

Bought this system wanting a IP based camera system. This system is an IP based system, although it doesn't have a builtin server like Arecount cameras costing tons more, this system works great and has a lot of bang for the buck, thank you Logitech! There is a caviot for macosx and Logitech should put it into the manual somewhere. I too had a problem seeing live video. It is because of UPD port 554 and Quicktime. If you cannot see live video, open Terminal application and type "qtdefaults write TransportSettings UDP 554". Another user pointed this out. Also, this system is fully PoE. You do not need the Power modules or Network receiver module dispite what Logitech helpdesk says. I have my system working using a Trendnet PoE 8-channel gigabyte switch. The MAC ALERT COMMANDER software, my network, PoE switch, and Cameras are all that is needed for an ethernet wired system. Have a minor unresolved storage issue. The software says there is suppose to be a browse button under tools, storage, cameras-- but I don't see one. My Mac system disk is full and with no browse option cannot move backup target to ext disk with current macosx commander software. An option to store video on a NAS or HDD like one that attaches to a Netgear WNDR4500 (nice to be via camera firmware, but system application is fine). Would be nice if Logitech would supply an arm box (plugs into network) that would interface an alarm system contact with the camera system to select a home mode and an away mode automatically. I have lots of video of family consuming precious memory space. I know the system has time presets, but many of us come and go frequently and an interface into the primary alarm box would be sweet. The cell phone app is great and works well. Be nice if it was formatted with time on bottom so one could pick out video clips around the times in question rather than just backing up from most recent. Overall, well done Logitech and thank you for supporting multiple platforms.

Feels like we've waited a decade for this, but anyway it's here and it seems well written. As a 1.0 version, it's five stars and I'm sure they'll fix the sore spots. You can't close the window without quitting the app which is silly. Also, every time you run it, you have to answer a silly question about which site you want to manage which since they know there is only 1 site is completely superfluous and interrupts the flow of launching the app. Since 99% of the time, you're running it in order to monitor the cameras or even at startup, that's not appropriate. Regardless, those are in the end fairly minor for an app that looks solid and doesn't seem to leave out any significant features from the Windows side.

Been waiting for this since I switched to Mac earlier this summer. So far it does everything that it did on my PC except play sound. There is no sound in live view or in my recordings. When I go to the website, I get sound in both the live view and recordings. When the App launches, sound is defaulted to the lowest setting, but there is still nothing once I slide the bar all the way up. Other than that, I love having this ability on my Mac, finally.****Update****Didnt realize I had to click on the live video feed of my only one and only camera to get the sound. Something I didnt have to do when I used the PC version. Got sound, given 5 stars now!
