RE: 4D 15.3HF1 OSX 10.12.4 - is 4D v15.4 the best answer.
Hi David, Honestly I focused on the v15.3HF1 vs 15.4 on macOS 10.12.x part of the question and completely missed that mention DDOS at all… Sorry. To be clear though, there is no v15.5 (yet) - there is a v15.4HF2 released a few days ago. The DDOS thread was solved by using v15R5 however this was certainly not (to my knowledge) on Sierra. Strictly speaking about macOS Sierra – - You should be using either v16.0 or v15.4+ because these are the versions that are certified for macOS Sierra. - V15.3/v15.3HF1 and v15R5 are not certified for macOS Sierra. Here is the v15R5 cert matrix: ftp://ftp-public.4d.fr/Documents/Products_Documentation/LastVersions/Line_15R5/VIntl/20160830_CertifV15_R5_INTL.pdf Regarding the DDOS thread – - I tested v15.4 (with a new db) using LOIC and I did not see an issue. - Randy tested 15R5 (his db) using LOIC and his crashing went away (while his db crashed in v15.4 during the ddos). My takeway from this is: Is v15.4 inherently bad at dealing with ddos attacks? No I don’t think so since a new db didn’t crash, it seemed to be something specific to the db’s that crashed. Is v15R5 inherently better at dealing with ddos attacks? Yes I think it is based on both Randy and Steve reports of their crashing going away with v15R5. Is v15R5 a good match for macOS Sierra? No absolutely not. Use v16.x if you want the features of the v15R release on Sierra.

RE: 4D 15.3HF1 OSX 10.12.4 - is 4D v15.4 the best answer.
Tim, Thanks for responding! We went to v15.3HF1 as a stop gap, because 15.2 was crashing on OSX 10.12.4. Why did you not recommend 4D v15.5? In a DOS attack posted here it performed without crashing, whereas 4D v15.4 crashed.
