OS Support for MacBook A1181

The Apple MacBook A1181, released in 2007, was part of a series of three generations that topped out at OS X 10.7.5. If you're using one of these computers with OS X Mavericks or later, you can install macOS Catalina.

Here is the list of supported models and their corresponding OS versions:

* MacBook A1181: 10.6.8

* Later MacBook generations (after the original MacBook1,1 Core Duo): 10.7

Additionally, if your computer meets certain specifications, you may be able to install macOS Catalina. These specifications include:

* 512MB or 2GB of 667MHz DDR2 SDRAM (PC2-5300) on two SO-DIMMs

* 1.83GHz or 2.0GHz Intel Core Duo processor with 2MB on-chip shared L2 cache

If you're experiencing issues with your MacBook A1181, resetting the NVRAM may help resolve them. To do this, press the power button and hold down Command-Option-P as soon as you turn on the laptop.

The original MacBook A1181 also came equipped with a number of features, including:

* Slot-loading SuperDrive with double-layer read support (DVD+R DL/CD- RW)

* 13.3-inch (diagonal) glossy widescreen TFT display with support for millions of colors

* Slot-loading Combo drive (DVD-ROM/CD-RW)

If you're looking to upgrade or replace your MacBook A1181, there are a number of replacement parts available online.
