My apple trackpad keeps losing its connection to my Mac mini. This just started happening. The trackpad will be connected and than not and than connected and than not. I have check the battery 97%. I can see it in the blue tooth screen when it is connected and not. I have not had the same trouble with my apple blue tooth keyboard.
You may want to make sure there is nothing interfering with the signal. Try moving the PC to a different area. Also make sure there are no other computers that are trying to connect to the keyboard and/or mouse.
You can buy and use a Bluetooth adapter. The Belkin Mini BluetoothV4.0 USB Adapter is described compatible with Mac and it is quite cheap.
