On a mac, there is this clever tool to turn off (parts of) applications that the computer thinks you are not using. This tool is called ‘app nap’.
For jamaseis, this has to be turned off. The following video shows how:
(Note: The initial part of the video shows how you can access the relevant settings by right clicking. You may need to hold down the control key on the keyboard while clicking to get to the contextual menus).
TC-1 on the left, connected through an Arduino and amplifier to the iMac
hardware
- 21″ iMac, c2008 model
- 3GB RAM
- 320GB HDD (divided into system and data partitions)
software environment
- MacOS X 10.9.x
- ESET NOD32 – antivirus
- Casper client – platform management
- Current JRE 7, JRE 6 (Arduino)
- jAmaseis
- Arduino IDE/drivers
- Owncloud desktop client – synchronization/backup
- Energy Saver
T
he energy saver settings are applied to the iMac using a policy in our Mac management tool, Casper (not to be confused with Kasper!). Even if these settings are modified by a local administrator, they will revert to those shown above when Casper refreshes the policy on the machine -if a School using one of these,needs us to modify the settings, we can unlock the policy -let Kasper know.
