Save your money: there are many freeware utilities such as MainMenu which do the same jobs (but with fewer bugs, greater ease of use, and better support) than this rip-off. I paid my full fee and got left without working software.

Every time a new major MacOS version comes out, the author of this software drops support for previous versions and releases a new one for which he expects all this customers to pay a full fee for.

I found this out after buying Panther Cache Cleaner (tcc's precursor) only to be left without software that didn't work. What happened was Apple released 10.4 before the 10.3.9 update came up. pcc support was dropped by the author: he supported Tiger Cache Cleaner only. Then Apple released the 10.3.9 update. This meant that pcc failed to work and existing pcc users were expected to pay a new full fee (not even a reduced price upgrade route) for tcc if they wanted to continue to use the functions they'd paid for.

I asked the author of pcc/tcc about this, as a paying customer, and he ignored me. Tiger Cache Cleaner is a pure rip-off and the business tactics uses by its author are probably illegal in the EU where I live.

I found out that there are free applications that do everything that pcc/tcc can do. MainMenu in particular works much better than pcc/tcc, the author is friendly and fixes problems very quickly. For example, rebuild LS database didn't work properly in either pcc or MainMenu - only checked the boot volume in both cases. MainMenu's author fixed the problem quickly when I told him about it. The author of pcc/tcc - software *I had purchased* - ignored the problem when I, a paying customer, reported it to him.
