Mac Enablement Notes

This page contains notes regarding the kernel team's effort to enable a sampling of Apple hardware.

Mac Mini 5,2 (CID 201112-10198)

Hardware Configuration

• CPU: Intel Core i5-2520M (SandyBridge) @ 2.50GHz, 2 cores x 2 threads

• Memory: 4 GB

• Storage: TOSHIBA MK5065GS

• Graphics: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] [1002:6741]

• Audio: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20]

• LAN: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe [14e4:16b4]

• WLAN: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331]

• SD Host Controller: Broadcom Corporation NeXtreme BCM 57765 Memory Card Reader [14e4:16bc]

• Firewire: Texas Instruments XIO2213A/B/XIO2221 IEEE-1394b OHCI Controller [Cheetah Express] [104c:823f]

Known Issues

• Sometimes hangs when trying to suspend (s3) or resume from suspend, not yet sure which.
• Wireless does not work well. Most of the time it is unable to associate with any networks.

MacBook Air 4,1 (CID 201112-10196)

Hardware Configuration

• CPU: Intel Core i7-2677M (SandyBridge) @ 1.80GHz, 2 cores x 2 threads

• Memory: 4 GB

• Storage: 120 GB SSD

• Graphics: Intel HD 3000 [8086:0116]

• Audio: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20]

• WLAN: Broadcom Corporation BCM53224 802.11a/b/g/n [14e4:4353]

Known Issues

• Power usage is high, about 10.5 to 11 W on average on an idle desktop. Enabling RC6 support in the i915 driver saves about 3 W, while the pm-utils changes currently being tested shave off another 1 W.
• Display artifacts are seen from time to time.

MacBook Pro 8,2, ATI graphics (CID 201112-10200)

Hardware Configuration

• CPU: Intel Core i7-2675QM (SandyBridge) @ 2.20GHz, 4 cores x 2 threads

• Memory: 4 GB

• Storage: Hitachi HTS54505 500 GB HDD

• Optical: MATSHITA DVD-R UJ-8A8

• Graphics: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] [1002:6741]

• Audio: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20]

• LAN: Broadcom Corporation NeXtreme BCM57765 Gigabit Ethernet PCIe [1434:16b4]

• WLAN: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331]

• SD Host Controller: Broadcom Corporation NeXtreme BCM57765 Memory Card Reader [14e4:16bc]

• Firewire: Agere Systems FW643 PCI Express1394b Controller [11c1:5901]

Known Issues

• Hangs trying to suspend (s3). I've done 50 consecutive s3 cycles successfully with the b43 module unloaded, so it's likely that this driver is to blame.
• Wireless does not work well. Most of the time it is unable to associate with any networks.
• Power draw is excessive when using the radeon driver, ~30 W on an idle desktop. Drops to ~15 W with fglrx.
• Cannot adjust display brightness.
• Gain on internal microphone is extremely low, even when set to max volume using sound settings.
