It was mentioned in some earlier posts regarding the same which I try to say but according to the sources, the most significant thing to check initially is to check first concerning an application, “What kind of application is it? ” as it ha s been found that there are normally PowerPC Universal, and Intel types of applications to be concerned about: PowerPC, Universal, and Intel.
PowerPC requires Rosetta and it has ben built in a way so that it will not run on OS X Lion. The other two Universal and Intel are well and they tend to be compatible with the OS X Lion which differ totally from the OS X lion. It will be best option for you if you are using an Intel based Mac and you are using Intel as an option. The Universal type comprise Intel and PowerPC support, but the latter can make the application bloated as well as the redundant PowerPC edition of the application on your Mac does not occupy enough space and due to this there is wasting of disk space.
You are also able to manually check each of your applications and for this you will require to click on its icon once to choose it and pressing CMD+I. You’ll observe a window open in Finder and you need to expand the General section if desired and look for “Kind.” It will come into view that the gpsWrite applications is PowerPC the only one which will not work on OS X Lion. After there was a successful installation of OS X Lion the icon for gpsWrite was turned into a “tombstone” . and I will say that the only solution for people with the desire to upgrade to OS X Lion and retain their Rosetta applications . you can try with the following if you are having enough knowledge regarding the skills, so If you are an advanced user and familiar with the Unix shell on your Mac you can try the command by opening the Terminal and enter the command.
Code:
system_profiler SPApplicationsDataType >~/Desktop/MyFileTypes.txt
and after this one, you will be having adequate information regarding the applications which is installed on your Mac by creating a text file on your Desktop then you need to open the document called MyFileTypes.txt present in the favorite text editor and search for the word “PowerPC” and each one of these will need Rosetta hold up in order to perform. In addition it is also said by the apple that until you don’t find an alternative for any other application , there is no requirement of upgrading. Apple has allegedly loosened the rules regarding virtualization of OS X to comprise the client account of OS X Lion. The server edition of Mac OS X Snow Leopard has had the aptitude to be virtualized under Fusion or Parallels for a little bit. It isn’t obvious if this aptitude to virtualize OS X will cover the client version of Mac OS X Snow Leopard or not. And if this is the case then you would be able to make use of virtualization on OS X Lion so that you are able to run Snow Leopard in order to get some additional mileage out of your apps that need Rosetta. Also apple has offered the rosetta and PowerPC support on Intel architecture machines for a couple of years.
