I don't have access to the logs, but I experience the same issue with the 0.2.0-prealpha version. The logs indicate that the app has fully caught up with the chain (the latest block height in the logs is equal to the latest block height on e.g. Blockexplorer). However, I get the warning

[info] /Applications/Lightning.app/Contents/Resources/assets/bin/darwin/lnd: 2018-07-05 11:44:36.791 [WRN] BTCN: Somehow we have 0 cfheaders for block 1 (00000000b873e79784647a6c82962c70d228557d24a747ea4d1b8bbe878e1206)

I think that this might be the problem. The chain is synced, but maybe not validated since the cfheaders for block 1 are missing?

@PJUllrich yes I created a new issue for prerelease. Closing in favor of #433
