Dropped features
Front Row[67], a media center application. The application has been copied into Lion by third-party users, however its incompatibility with iTunes 10.4 renders it useless.[68]
Rosetta, software which makes possible the execution of PowerPC software on x86 hardware, is no longer available.[67] This disables some programs that ran on previous versions of Mac OS X.[69] Programs requiring Rosetta to operate are not allowed to be distributed via the Mac App Store.[70]
Adobe Flash Player and Apple's Java Runtime Environment (JRE) are not included in new installations of Lion, but both can still be downloaded and installed manually.[67][71][72] Apple will no longer be actively maintaining its JRE, but Software Update will offer to download Snow Leopard's JRE if a user tries to run a Java program without there being a JRE installed.[73] Programs using Java are not allowed to be distributed via the Mac App Store.[70]
iSync, software used for syncing contacts and calendars to third-party mobile phones, is no longer included; however, iSync v3.1.2 from Snow Leopard continues to work.[citation needed]
Remote Install Mac OS X, software which allows OS X to be installed using the Remote Disk feature. Using Target Disk Mode, users can circumvent this omission.[74][75]
Apple USB Modem is not compatible with Lion.[76]
