Can't get back to mac partition after installing Windows 7 64bit without support files.

Last night I ran Boot Camp to install Windows 7 64bit on my mid 2013 13" MacBook Pro i7 2.9ghz. I went online to get the support files and found that they were not abailable. I went ahead without the files and partitioned and installed Windows. Now I understand the purpose of the support files. I can't get back to the Mac partition to use the Mac OS and have no drivers to effectively use the Windows partition. Is there a remedy that I can use at home or do I need to take the machine to an Apple store?
