XLR8, the folks who make multiprocessor upgrades and expansion products for the Mac, have revised their cache enabling and PowerPC processor optimization software, MACh Speed Control 2.6.0, to make it work better with — you guessed it — Mac OS X v.10.1.
In addition to OS X 10.1 compatibility, MACh Speed Control 2.6 adds thermal monitoring of PowerPC G3 and G4 processors while running under Mac OS X, as well as improved stability and enhanced Velocity Engine support, according to David Reynolds, XLR8 product manager.
However, this version of the MACh Speed Control software contains full dual processor (Mach Carrier G4 MPe or the MACh Velocity G4 Mpe) support only for OS X 10.0.4. Multiprocessing support for OS X 10.1 will be included in MACh Speed Control 3.0, due next month. And note that Mach Speed Control 2.5 doesn’t offer dual processor support for the Mach Carrier G4 MPe or the MACh Velocity G4 Mpe under Mac OS X 10.1. So don’t use it with the dual-processor Mach Velocity under OS X 10.1.
You’ll need a valid XLR8 serial number to install MACh Speed Control 2.6. XLR8 customers who purchased their upgrade after January 2000 received a serial number with their cards. Other users of XLR8 or 3rd party upgrades may purchase a serial number for US$14.95
online. However, if you’ve installed MACh Speed Control 2.5, there’s no need to input your serial number; the update will search your hard drive for the number.
