Minimum Requirement: Windows: Intel Core 2 Duo (or AMD equivalent) processor with 3GB of RAM. Mac: Almost any Mac that runs OS X 10.8 or later released in 2011+ with 3GB of RAM.
Recommended: Windows: Modern quad-core processor with 4GB of RAM or greater. This includes the Intel Core 2 Quad and Intel Core i3, i5, and i7 processor lines (or their equivalent AMD processors). Mac: Almost any Mac that runs OS X 10.7 or later released in 2011+ with 3GB of RAM.
Optimal: Windows: Intel Core i5 or i7 multi-core 64-bit processor with 8GB of RAM or greater. Mac: Any Mac released in 2013+ with an SSD hard disk such as the Macbook Pro Retina line of laptops with 8GB of RAM or greater.
Not Recommended: Windows: Intel Pentium 4, Atom or other low power processors such as ARM.
Minimum Requirement: Windows: Windows Vista, Windows 7, Windows 8, 8.1 or Windows 10. Mac: OS X Snow Lepard 10.6, OS X Lion 10.7, OS X Mountain Lion 10.8, OS X Mavericks 10.9, OS X Yosemite 10.10, OS X 10.11 El Capitan or macOS Sierra 10.12.
Recommended: Windows: Windows 7+. Mac: OS X Yosemite 10.10+
Minimum Requirement: PostgreSQL 8.3.18 or greater (Windows only) / PostgreSQL 8.4.12 or greater / PostgreSQL 9.0.7 or greater
Recommended: Manually install the latest version of PostgreSQL 9.3.x.
Optimal: Manually install the 64 Bit version of PostgreSQL 9.3 or later. This requires a 64 bit processor and Operating System, with 8 Gigs or ram or better for optimal performance.
Not Supported: PostgreSQL 9.4 is not supported due to potential database errors, for the best performance please use PostgreSQL 9.3 or greater.
The number one factor for speed performance is hard drive speed, the PostgreSQL Server which powers the PokerTracker database commonly moves gigabytes of data to allow PokerTracker 4 to perform it's reporting duties. PokerTracker recommends at least a 7200RPM hard drive or faster, Solid State Drives (SSDs) are currently the fastest drives available for optimal performance. The optimal solution for Mac users are computers that contains a built in SSD drive such as 2012's Macbook Airs (idealy with 4Gigs Ram or greater) or Macbook Pro Retina laptops.
Your PostgreSQL password was chosen when you initially installed PostgreSQL (whether by the PT4 installer or manual installation). Most users will find one of these passwords to work:
If the above passwords do not work or you do not remember the password that you created, you can configure PostgreSQL to not require a password: How To: Remove PostgreSQL Password
