Perhaps someone who has upgraded can speak to that question.

I don't know if it works in High Sierra because I haven't upgraded from Sierra yet. So despite the lapse in development, I don't regret the money I spent on the original and the upgrade. Even so, it still works, with a quirk of two. Sadly it seems to be the case that development ceased in 2014. I saw no recent comments there in any case. Sadly the product web site was deactivated last month. I don't recall, unfortunately, how you switch between the two, or insure one or the other is used for a specific application. In order to get better performance you need to be sure you are using the more powerful video card. The computer will use a portion of the system RAM in order to conserve battery life. I suspect those having trouble with Marine Aquarium may be using a Mac laptop with dual video RAM. And, finally, the app holds my registration. The application, on the other hand, gives me access to all the fish and I can show up to twenty-two of them at a time-even though the limit is still set at eight. But they will be duplicates of one or another of the fish in the base set.
#Large number mac screen saver serial number
The registration field is blank every time I reopen the settings and they won't close unless I paste in the serial number again.Īnother interesting issue: The screen saver is limited to seven different kinds of fish-though I can show more fish if I want to. For some reason, though, the screensaver will accepts but won't hold my serial number. From there, you can press on the power button again to wake it up and you should be back at your desktop.Īgain, this is a temporary fix and it’s likely that you’ll come across this issue again at some point in the future if you don’t take further steps, but it will at least prevent you from having to shut down your Mac and possibly lose any important work that you were in the middle of.Version 3.2.1 works reasonably well on my 27" iMac running macOS 10.12.6. This will manually put your Mac to sleep. If you happened to be working on something important when the screensaver problem occurred (maybe you went to get a quick drink and came back to it), you don’t necessarily want to force-shutdown your Mac in the middle of important work, so there’s a temporary fix that will unfreeze your Mac’s screensaver.Īll you have to do is press down on the power button for about a second (a quick tap won’t do it). Put It to Sleep Manually and Wake It Back Up If it doesn’t happen again, then it’s likely that resetting the NVRAM helped.

Of course, you won’t know if this has actually fixed the screensaver problem until it happens again. From there, let go and let your Mac boot up as normal. To reset the NVRAM, start by completely shutting down your Mac. Next, press the power button to turn on your Mac, and immediately press Cmd+Opt+P+R on your keyboard. Keep holding those keys down until you here the startup chime for the second time. Keep in mind, though, that this will reset things like speaker volume, mouse settings, date and time, and other small things like that. Sometimes the NVRAM can become corrupted, which could cause an issue like this. It stores various OS X data like speaker volume, mouse and trackpad settings, and screen resolution. The only quick, permanent solution that I’ve seen fix this problem is resetting the NVRAM (non-volatile random-access memory). I’ve personally seen it happen on my MacBook every few months or so, but there are a couple of fixes that you can try out. We’re not exactly sure why it occurs, but it’s a known reoccurring issue. Furthermore, your Mac may also never go to into sleep mode because of this and will remain on until you can fix the problem and get back to the desktop. The keyboard and mouse will still work, meaning that if you click your mouse or type on your keyboard while your screensaver is frozen, your Mac will still register it. The mouse cursor will appear on the screen and you can freely move it around, but the screensaver will still show. If your Mac’s screensaver freezes, moving your mouse cursor around or hitting keys on the keyboard won’t make it go away.
